Proxy showing blank page - Solved

@usmannasir There’s an issue with this tutorial on How to remove port 8090 from CyberPanel - Blog Posts - CyberPanel Community

I am running a discord webhook proxy service using it, and after 24 hours, the whole page shows internal error 503 while server IP:port works fine.

I asked on OLS forums, but they said to ask here.
ExtConn timed out while connecting. CyberPanel | OpenLiteSpeed Community and News

Any idea what could cause it?

Below is an image from HTTP://IP:port

This is the webhook I’m running.
