Reverse proxy is giving me 404 errors

[unixandria]

Hello!

I finally got my two wordpress sites up and running with OLS and also my Matomo instance running.

However, I'm having some issues getting reverse proxy to work.

I have three websites that need to reverse proxy: a GitLab instance, a Bitwarden instance, and a Jenkins instance.

I've set up a websocket proxy for each: gitlab to the workhorse socket, jenkins to localhost:7070 where its listening, and bitwarden I have to use external app + context since /notifications/hub needs to go to docker-network:3012 and everything else to doker-network:80

However each just shows a 404 error page.

My host machine is a dedicated server running ubuntu 20.04,

Here are the relevant parts of my old Caddyfile that worked, because i'm not 100% sure how to translate it to OLS.
