Why Choose CloudPanel for Domain-Port Mapping?

CloudPanel simplifies connecting domains to custom ports through its web-based interface. Unlike traditional methods that need NGINX expertise, CloudPanel handles all the configuration.

Key advantages of adding your domain with ports include:

• Visual domain management
• Automatic SSL certificate handling
• No manual NGINX editing
• One-click port routing
• Built-in security features

Common Use Cases for CloudPanel Domain Mapping

Use Case	Example Domain Mapping	Purpose/Benefit
Development Environments	- staging.myapp.com → Port 3000 - staging-api.myapp.com → Port 8080 - staging-admin.myapp.com → Port 3001	- Spin up isolated dev or staging sites, & test new features without breaking production. - Map backend APIs for QA and dev teams. - Create separate admin panels for testing without exposing them to customers.
Microservices Architecture	- auth.myapp.com → Port 4000 - data.myapp.com → Port 4001 - files.myapp.com → Port 4002	- Place clean, memorable URLs for each service. - Decouple data services for better scaling and security. - Route file storage or uploads through a dedicated subdomain.
Several Applications	- blog.mydomain.com → Port 3000 - shop.mydomain.com → Port 3001 - dashboard.mydomain.com → Port 3002	- Run a blog, shop, and dashboard on one system, each with its clean URL. - Launch new products or shops fast, without extra hosting costs. - Give internal teams their dashboard, separate from customer-facing sites.
API Gateway/Reverse Proxy	api.myapp.com → Port 5000	Centralize API traffic, add security, and simplify client-side connections.
White-label Solutions	client1.yourplatform.com → Port 6000	Offer branded portals for clients, each mapped to their subdomain.
Legacy App Modernization	legacy.myapp.com → Port 7000	Keep old apps running behind modern, secure URLs without rebuilding everything.

How CloudPanel Handles Port and Domain Management?

CloudPanel provides tools to handle and treat domain-port mapping as a fundamental feature. The platform recognizes that modern applications often run on 'non-standard ports'.

When you add a domain in CloudPanel, the system:

1. Creates the necessary proxy configurations.
2. Manages SSL certificates.
3. Sets up proper headers for optimal performance.
4. Implements security rules.

Domain-Port Mapping: CloudPanel vs. Manual Configuration

Feature	CloudPanel Domain-Port Mapping	Manual NGINX Configuration
Setup Speed	Lightning fast; add a domain and set the port in a few clicks.	Slow; write config files and reload NGINX.
Skill Needed	Zero command-line; anyone can do it from a web dashboard.	Command-line only; you must know 'NGINX syntax' and 'server basics'.
SSL Management	Automatic; built-in Let’s Encrypt and self-signed SSL with one click.	You generate, install, and renew certificates yourself.
Diagnostics	Built-in visual status indicators, logs, and error tracking in the UI.	Manual log digging and no visual cues; you tail logs, grep errors, and troubleshoot by hand.
Reverse Proxy	Integrated. Set the app port in settings; CloudPanel handles NGINX reverse proxy.	You write your own proxy_pass rules, set headers, and manage upstreams.
Domain Redirection	Automatic 'www/non-www' and HTTP > HTTPS redirects.	Manual. You must add 'server blocks' and rewrite rules for each redirect.
Backups & Rollbacks	Automated backups and easy restores from the dashboard.	No built-in backup/rollback. You script it yourself or risk losing configs.
Multi-Site Management	Manage many domains, apps, and ports from one dashboard.	Each new domain/port is a new config file, which can get messy fast.
Visual Feedback	See everything in a clean UI. Errors, logs, and SSL status are all available in one place.	No visual feedback; all CLI.
Security Features	One-click Basic Auth, IP-based whitelisting, and more from the UI.	You hand-edit the config for every security tweak.
Customization	Vhost editor for advanced tweaks, but most use cases are point-and-click.	Full control, but every change is manual and error-prone.
Learning Curve	Minimal; anyone can learn it in minutes.	Steep; you need to know NGINX, Linux, and SSL basics.
Who’s It For?	Teams, agencies, independent devs, or anyone who wants to move fast and not manage configs.	Sysadmins/NGINX power users/anyone who loves living in the terminal.

4 Steps to Add a Domain with Custom Port in CloudPanel

Step 1: Access Domain Management

1. Log in to your CloudPanel dashboard.
2. Go to 'Domains' in the sidebar.
3. Click "Add Domain".

Step 2: Integrate Basic Domain Settings

1. Enter your "domain name" (e.g., api.yourdomain.com).
2. Select the "site" to which this domain should point.
3. Choose the "port" on which your application runs.

Step 3: Port Specification

CloudPanel allows you to specify any port for your domain by letting you:

1. Enter the 'port no.' (e.g., "8080", "3000", "5000").
2. CloudPanel creates the proxy configuration.
3. The system validates that the port is accessible.

Step 4: SSL Configuration

CloudPanel handles SSL with the following processes:

• Generates a Let's Encrypt certificate.
• Integrates HTTPS redirects.
• Sets proper security headers.

Troubleshooting Domain-Port Issues in CloudPanel

Issue	CloudPanel Diagnostics Tool	Action Steps
Domain not resolving	Domain connectivity checker	- Check 'DNS settings' in CloudPanel. - Verify domain ownership. - Wait for 'DNS propagation'.
SSL certificate errors	SSL certificate validator	- Regenerate the certificate in CloudPanel. - Check domain validation. - Clear browser cache.
Port connection failures	Port accessibility tester	- Make sure your app is running. - Check that the port is active and not blocked. - Review CloudPanel logs.
Unknown errors	Log viewer	- Check error logs for clues. - Search for common error codes. - Restart CloudPanel service.
