Hi, just tried to setup Discourse and all went good except for launching it. It gives the following error: starting up existing container + /usr/bin/docker start app Error response from daemon: Cannot start container app: Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already …

[imagem] Run other websites on the same machine as Discourse Self-Hosting If you want to run other websites on the same machine as Discourse, you need to set up an extra NGINX or HAProxy proxy in front of the Docker container. NOTE: This is for advanced admin…

Thanks for the quick reply, I am not sure though if I am capable of doing all of that, I am really a beginner with Linux and the stuff there seems quite tricky, especially since it has to be configured with other webservices as well (Or so it seems according to the last part of the guide, suggestin…

I managed to get it running (the container, that is) but I don’t really understand yet what port it runs on and how I can access it. forum.mydomain.com gives me nothing, probably because I haven’t set up DNS yet? and wouldn’t know where else it should be on. :4001 doesn’t work either but tinkering w…

I set up nginx correctly with atleast Discourse, but I still can’t acce…
