Steps to reproduce

I simply started using Vaultwarden today and noticed the errors in the logs (will provide examples later)

Expected behaviour

Working websocket connections. :)

Actual behaviour

I see 502 errors in every logs, for example, the nginx error log:

Docker logs:

[2022-12-02 21:27:13.872][vaultwarden::api::notifications][ERROR] 
    ###########################################################
    '/notifications/hub' should be proxied to the websocket server or notifications won't work.
    Go to the Wiki for more info, or disable WebSockets setting WEBSOCKET_ENABLED=false.
    ###########################################################################################

Also, when I look up https://warden.domain.tld/notifications/hub in my browser, I get a 502 error right away.

If I check inside the container, I get this:

docker exec -it vaultwarden curl 127.0.0.1:3012
curl: (52) Empty reply from server

Troubleshooting data

I tried multiple different websocket configs (from the examples in the wiki, from my previous configs, etc), with no prevail.

I would be grateful for any pointers.

Go to the Wiki for more info, or disable WebSockets setting WEBSOCKET_ENABLED=false. ########################################################################################### ``` Also, when I look up https://warden.domain.tld/notifications/hub in my browser, I get a 502 error right away. If I check inside the container, I get this: ```shell docker exec -it vaultwarden curl 127.0.0.1:3012 curl: (52) Empty reply from server ``` ### Troubleshooting data I tried multiple different websocket configs (from the examples in the wiki, from my previous configs, etc), with no prevail. I would be grateful for any pointers.
