502: Error reading from remote server (Apache Reverse Proxy)

[Maschda]

Issue

I have a fresh install of the latest version of Tandoor and i cant access the Website threw my Apache reverse proxy. Al i get is "502: Error reading from remote server". If i try to access the nginx container directly, the website does not load, or give any response back.

Has had anyone the same issue? Or can help me resolve it?

I would realy appreciate it. Thanks!

PS: If another Proxy is simply a better choice, im not bound to Apache.

nginx runs on port 80 what are you trying to accomplish here?

  nginx_recipes:
    ports:
      - 8081:8080

[Maschda]

hm, i had it on 8080:8080. My understanding is that I select the port on which the nginx reverse proxy in this container is listening on. My reverse proxy forwards the connections from 443 to port 8080.

nginx proxy listens on port 80

Ok, i changed it back to 80 and now i can see a website. Without the Logo and everything looks a bit messed up. Then I tried the alternative Apache reverse proxy configuration from beedaddy and everything seems to work. Thank you!
