5 Steps to Resolve CloudPanel FTP Not Working Issues in 2025

5 Steps to Resolve CloudPanel FTP Not Working Issues in 2025

Are you struggling with CloudPanel FTP not working issues? CloudPanel v2 uses ProFTPd 1.3. x as its primary FTP server. But configuration challenges can still arise that prevent successful connections.

This tutorial covers how system administrators can resolve CloudPanel FTP not working issues.

Key Takeaways

  • Username configuration requires a "-ftp" suffix & correct 'home directory' variables in CloudPanel v2.
  • 'Directory permissions (755)' & 'file ownership' must match the 'FTP users' for transfers.
  • Firewall rules must allow 'port 21' and the 'passive port range' 49152-65534.
  • Passive mode requires proper MasqueradeAddress settings in /etc/proftpd/proftpd.conf.
  • Log analysis reveals error patterns for persistent troubleshooting.
  • CloudPanel's built-in file-based manager offers an alternative when FTP troubleshooting becomes time-consuming.
  • WordPress users need specific directory matching for content access and plugin installation.
  • 'SSH' and 'FTP user' conflicts need proper group membership configuration.

How FTP Works in CloudPanel v2?

1. 'User Account' and 'Directory Assignment'

CloudPanel v2 creates 'FTP users' with specific folder access on your server. Each 'account' has a 'site user' and 'restricted access' to that site's directory structure. This approach leads to connection failures if directory permissions are not set up.

2. Connection Establishment Process

Connections are set up using an FTP client (e.g., 'FileZilla', 'WinSCP') by entering:

  • Your server's 'IP address' or 'hostname'
  • Username/password (with the "-ftp" suffix in CloudPanel v2)
  • Port 21 (standard FTP port)

CloudPanel authenticates these credentials. Based on the site user configuration, it also maps them to the appropriate directory.

3. File-Based Transfer and Management Capabilities

Once established, users can upload/download/rename/delete 'files' within their assigned directories. This flexibility allows you to manage sites without granting full server access. It is necessary for WordPress sites where plugin & theme installations need FTP credentials.

4. Passive Mode and Port Configuration

CloudPanel's ProFTPd implementation supports passive mode FTP. It is necessary when establishing a link behind firewalls or NAT devices. In passive mode:

  1. The client initiates the connection to "port 21".
  2. The server activates a random high port in the passive range ("49152-65534").
  3. Data/file transfers occur over this passive connection.

This process enables proper firewall configuration for successful FTP operations in CloudPanel environments.

5 Steps to Fix CloudPanel FTP Not Working Issues

Step 1: Verify User Setup and Permissions

i. Create and Configure 'FTP Users'

  1. Log in to your CloudPanel dashboard.
  2. Navigate to 'Users' > 'FTP Users'.
  3. Click 'Add User' and enter:
  • Username (CloudPanel includes "-ftp" suffix)
  • Strong 'password' meeting security requirements
  • 'Home directory path' (e.g., /home/username-ftp/)
  1. Click ‘Add User’ to create the 'account'.

Note: Verify your FTP client if you've created a user but can't establish a link. It must include the "-ftp" suffix that the CloudPanel v2 appends to usernames.

ii. Fix Directory Permissions

Most access issues stem from incorrect permissions. Follow these steps to identify and fix permission problems:

  1. Check current ownership and permissions using:

ls -la /path/to/directory

  1. If permissions need modification, run these commands:

  2. Set ownership for the user's 'home directory' via:

chown username-ftp:username-ftp /path/to/directory

  1. Set proper directory permissions ("755" for directories, "644" for files) with:

chmod 755 /path/to/directory

find /path/to/directory -type f -exec chmod 644 {} \;

find /path/to/directory -type d -exec chmod 755 {} \;

  1. For WordPress installations, ensure the wp-content directory has the correct permissions by running:

chown -R username-ftp:username-ftp /path/to/wordpress/wp-content

chmod -R 755 /path/to/wordpress/wp-content

iii. Resolve 'SSH' and 'FTP User' Conflicts

A common issue in CloudPanel involves conflicts between 'SSH key logins' and 'FTP users'. After creating an 'FTP account', 'SSH access' for the same site user might stop working. To fix:

  1. Check user groups with:

groups username

  1. Ensure the user belongs to both the 'SFTP group' and appropriate 'system groups' using:

usermod -aG sftp,www-data username

  1. Reset permissions if needed by running:

chown -R username:username /home/username

Step 2: Configure Firewall & Ports

cloudpanel firewall and port configuration for ftp access including port 21 and passive port range 49152–65534

Firewall restrictions often block FTP connections. It is because many cloud providers disable conntrack helpers by 'default'.

i. Configure Required FTP Ports

Your CloudPanel server needs these ports 'open':

  • TCP Port 21: Standard 'FTP command port'
  • TCP Ports 49152-65534: 'Passive port' range used by ProFTPd

To update your CloudPanel v2 firewall:

  1. Go to Admin Area > Security > Firewall.
  2. Set a rule for "port 21" (for your 'IP' or all 'IPs' as needed).
  3. Enable the ProFTPD 'Passive Ports' rule, which activates ports "49152-65534".
  4. Save and apply the settings.

a. Verify firewall rules with (for "UFW") using:

sudo ufw status verbose

b. Configure "iptables" via:

sudo iptables -L -n

ii. Set Up Passive Mode Configuration

Many cloud providers disable the conntrack helpers that manage passive FTP connections. Check these steps to configure 'passive mode' in a manual way:

  1. Go to Admin Area > Settings > ProFTPd Settings.
  2. Edit /etc/proftpd/proftpd.conf1 via 'SSH' by running the command:

sudo nano /etc/proftpd/proftpd.conf

  1. Configure or update these configuration lines using:

PassivePorts 49152 65534

MasqueradeAddress your.server.ip.address

  1. Replace your.server.ip.address with your actual 'public IP-based settings'.
  2. Save the file & restart ProFTPd by going to Admin Area > Settings > ProFTPd Settings. Then, run the command below:

sudo systemctl restart proftpd

iii. Check for 'IP Changes' and 'Server Migrations'

Update your MasqueradeAddress setting to reflect the new 'IP' address. This process is especially necessary when moving between 'cloud providers'/changing 'networking configurations'.

Step 3: Fix Specific Connection Problems

i. "Connection Refused" Errors

When you can't establish a connection at all, follow these troubleshooting steps:

  1. Check if ProFTPd is running using:

sudo systemctl status proftpd

  1. Look for competing FTP servers by running:

netstat -tulpn | grep :21

  1. Test local connection via:

telnet localhost 21

  1. Check for package conflicts with:

dpkg -l | grep -i ftp

Note: The latest version uses systemd for service management. If ProFTPd isn't running, use the command below:

sudo systemctl start proftpd

sudo systemctl enable proftpd

ii. "Failed to Get Folder List" Errors

When you establish a link but can't see files:

  1. Enable 'passive mode' in your FTP client settings.
  2. Verify your firewall allows the 'passive port' range ("49152"-"65534").
  3. Check that your MasqueradeAddress matches your server's public 'IP'.
  4. Try using FileZilla's "Force showing hidden files" option.
  5. Test with an alternative FTP client like "WinSCP" or "Cyberduck".

For example:

  1. Go to Settings > Connection > FTP > Passive mode.
  2. Select "Use passive mode".
  3. Deselect "Fall back to active mode" if experiencing issues.

iii. WordPress-Specific Issues

WordPress users encounter "Unable to locate WordPress content directory" errors when installing plugins. To resolve:

  1. Ensure the FTP user's 'home directory' matches 'WordPress's location'.
  2. Verify the 'FTP user' has 'read/write access' to the 'wp-content directory'.

a. Grant proper ownership using:

chown -R username-ftp:username-ftp /path/to/wordpress/wp-content

b. Set proper permissions using:

find /path/to/wordpress/wp-content -type d -exec chmod 755 {} \;

find /path/to/wordpress/wp-content -type f -exec chmod 644 {} \;

  1. For different WordPress sites on a single server, create separate FTP 'accounts'. Do this for each site with proper directory mapping.

Note: When prompted for 'FTP credentials', include the "-ftp" suffix in your username.

Step 4: Use Troubleshooting Logs

i. ProFTPd Logs Analysis

  1. Check the server logs at /var/log/proftpd/proftpd.log using:

a. View live log updates using:

tail -f /var/log/proftpd/proftpd.log

b. Search for specific error patterns with:

grep 'failed login" /var/log/proftpd/proftpd.log

grep "permission denied" /var/log/proftpd/proftpd.log

  1. Check the common error patterns and their solutions:
Error Pattern Likely Cause Solution
USER username-ftp: no such user Username doesn't exist Create a "user" in CloudPanel
unable to set 'default' permissions Directory permission issues Reset "ownership" and "permissions"
Connection refused ProFTPd not running Start 'ProFTPd' service
Passive 'data' transfer failed Firewall blocking 'passive ports' Activate the 'passive port' range

ii. Client-Side Diagnostics

  1. 'FileZilla' offers detailed error messages in its log section (View > Message Log). When establishing a connection, ensure your settings include:
  • Correct server address ('IP' or 'hostname')
  • Username with "-ftp" suffix (if created in CloudPanel v2)
  • Accurate 'password'
  • Port 21 for "standard FTP"
  1. Go to Admin Area > Logs admin interface for improved logging with timestamp filtering.

Step 5: Advanced Fixes

i. Resolve FTP Server Conflicts

CloudPanel v2 installs and uses ProFTPd by 'default'. Installing another FTP server, like 'vsftpd', creates conflicts. If you've installed a competing server:

  1. Remove the conflicting FTP server via:

sudo apt remove vsftpd

  1. Reinstall ProFTPd if needed using:

sudo apt install proftpd-basic

  1. Reconfigure with:

sudo dpkg-reconfigure proftpd-basic

  1. Choose "standalone" mode when prompted.

ii. Post-Migration Fixes

After altering IPs or moving to a new server:

  1. Update MasqueradeAddress in your ProFTPd config.

a. Find your public 'IP' using:

curl -4 icanhazip.com

b. Edit the configuration file via:

sudo nano /etc/proftpd/proftpd.con

c. Update MasqueradeAddress with new 'IP' using:

MasqueradeAddress your.new.ip.address

  1. Adjust firewall rules for the new 'IP'.

  2. Restart ProFTPd via:

sudo systemctl restart proftpd

  1. Update 'DNS records' if using 'hostnames' for FTP connections.

iii. Performance Optimization for FTP Transfers

For users experiencing slow FTP transfers in CloudPanel v2:

  1. Edit /etc/proftpd/proftpd.conf by running:

sudo nano /etc/proftpd/proftpd.conf

  1. Optimize these performance optimizations:

MaxInstances 30

MaxClients 10

MaxClientsPerHost 3

MaxClientsPerUser 2

MaxHostsPerUser 5

Umask 022

AllowOverwrite on

  1. Restart ProFTPd using:

sudo systemctl restart proftpd

Alternative File Transfer Methods in CloudPanel

. SFTP ('SSH File Transfer Protocol')

SFTP offers encrypted file transfers using the 'SSH protocol'. This approach helps you avoid many common FTP issues by letting you:

i. Establish a link using 'port 22' instead of port 21 ii. Use the same username without the "-ftp" suffix. iii. Support "no passive mode" configuration. iv. Enable "most firewalls" without special configuration.

To enable SFTP for a user in CloudPanel v2, follow these steps:

i. Go to Sites > [Your Site] > SSH/SFTP Users. ii. Create or edit a user with 'SSH access' enabled. iii. Establish a link using 'SFTP' in your file transfer client.

2. CloudPanel's Built-in File Manager

cloudpanel built-in web-based file manager as an alternative to ftp and sftp for secure file operations

CloudPanel v2 includes a web-based file manager that works without any extra configuration. Consider these steps:

i. Log in to the CloudPanel dashboard. ii. Navigate to Sites > [Your Site] > File Manager. iii. Browse/upload/download/adjust files through the web interface.

This solution works even when FTP and SFTP are unavailable. Thus, it makes it an excellent fallback option.

3. WebDAV Integration

For advanced users, CloudPanel can be set up with WebDAV for file transfers. Consider the following steps:

i. Install the required packages by running:

sudo apt install apache2-utils libnginx-mod-http-dav-ext

ii. Configure NGINX for WebDAV. iii. Establish a link using a WebDAV-compatible client.

FAQs

1. Why isn't my CloudPanel FTP access working?

CloudPanel FTP issues arise from incorrect user setup, permission conflicts, or firewall blocks. First, check if your username includes the "-ftp" suffix CloudPanel v2 sets up. Then, verify directory permissions ("755" for directories, "644" for files). Ensure ports 21 & 49152-65534 are active in your firewall.

2. How to set up an 'FTP user' in CloudPanel v2?

Navigate to 'Users' > 'FTP Users' in the CloudPanel dashboard and click 'Add User'. Enter a username (CloudPanel includes "-ftp") and a strong 'password'. Specify the correct home directory (e.g., /home/username-ftp/) and click 'Add User'. Remember to configure proper directory permissions and firewall rules for successful connections.

3. How to find the cause of CloudPanel FTP problems in the logs?

Look for error patterns like failed login attempts/permission denials/configuration problems. In CloudPanel v2, you can access logs through the Admin Area > Logs web interface. Use client-side diagnostics like FileZilla's message log for detailed error information.

4. How do I fix FTP issues after the CloudPanel server migration?

Update the MasqueradeAddress in the ProFTPd configuration with your new 'IP' address. Adjust firewall rules to allow FTP traffic through port 21 & the 'passive port' range. Restart ProFTPd with systemctl restart proftpd. Then update 'DNS records' if you use hostnames for FTP connections. Also, verify that user permissions and directory structures migrate well.

5. Why doesn't FTP work for WordPress plugin installation in CloudPanel?

WordPress users often experience the error "Unable to locate WordPress content directory". It is when the FTP user's home directory doesn't match the WordPress installation path. Ensure your FTP user's home directory matches the WordPress site's root directory. Verify that the 'FTP user' has read/write access to the wp-content directory. You can set proper ownership with chown username-ftp:username-ftp /path/to/wordpress/wp-content.

6. How do I resolve conflicts between 'SSH' and 'FTP users' in CloudPanel?

Conflicts between 'SSH key logins' & 'FTP users' occur when group memberships aren't configured. Check user groups with the group's username. Ensure the user belongs to the SFTP and appropriate system groups (e.g., "www-data"). Use usermod -aG sftp and www-data username. Reset permissions if necessary with chown -R username:username /home/username. In CloudPanel v2, proper group configuration is set up during user creation.

7. How to optimize FTP transfer speeds in CloudPanel?

Configure the ProFTPd settings with optimal values. Set appropriate MaxInstances, MaxClients, and buffer size values. Ensure your server has adequate CPU and memory resources. Consider switching to SFTP for better performance with large files. CloudPanel v2's built-in file manager performs better than traditional FTP for some operations.
