Originally created by @ProudlyTM on GitHub.

I am running a separate docker nginx server and I'm trying to proxy pass to the internal nginx server of the Bitwarden_RS container, except I have apparently configured something wrong, since I keep getting Error 502 when I try to access the web-vault.

This is what my own docker nginx server subdomain config looks like as of now.

Notes worth mentioning:

When I initially ran the image, I exposed internal port 80 to external port 8383, since port 80 is already bound to my own docker nginx server.
I have not changed anything in the docker image's included nginx server.

Any help will be appreciated. Thanks.

I resolved this by changing "http://bitwarden:8383" to "http://bitwarden:80".. I didn't realize I was trying to reach a non-used port to the docker container of bitwarden itself. 🤦‍♂️😄
