how are you ? Today I'm with this problem that I cannot solve.
I created an instance to which I associated a docker container using cyberpanel, so far so good since if I enter the URL of the instance including the port I can use the app correctly. Now, I am trying to use the main domain of the instance as if it were the domain with the port and for this I used:
RewriteEngine On
RewriteRule ^(.*)$ http://localhost:9000/$1 [P,L]
When doing this my app is returning an error code 500.
Also, I tried to add in the OpenLiteSpeed panel (in the corresponding virtualhost) an "External App" that points to the url with the port.
I am using cloudflare also to reach the instances.
Some clue ? Thank you very much and have a good day / night
