Discouse passes localhost uri as oauth redirect_uri

[riking (Kane York)]

Edit: Forgot to mention, the container isn’t directly binding port 80/443, but being proxied through an nginx, since the host serves other sites as well.

Did you forget this part of the nginx config?

Running other websites on the same machine as Discourse

proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $proto;
