Troubleshoot OpenLiteSpeed Proxy Issues

I need assistance with OpenLiteSpeed and CyberPanel on my VPS. I can access Cockpit and Immich directly via the host, but when I try to proxy them to a domain or subdomain, their features are timing out.

Requirements:
- Familiarity with OpenLiteSpeed and CyberPanel
- Experience troubleshooting proxy issues
- Ability to identify and fix misconfigurations

Ideal Skills:
- Server management
- Proxy configuration
- Problem-solving skills

I'm looking for someone who can quickly diagnose and resolve the timing out issues.
