Hi all !

I have following this wiki : https://github.com/dani-garcia/bitwarden_rs/wiki/Proxy-examples for enable HTTPS with Traefik V2 but i get "Bad Gateway" when I try to access on my URL bitwarden.mydomain.com.

The certificate is correctly create by lets enscript on my file "acme.json".

My Traefik configuration :

My Bitwarden configuration :

The Traefik's logs when I try to access to my "bitwarden.mydomain.com" :

And the page than I get :

I don't see where the problem can come... We can see in the logs that Traefik redirects the url to the docker address of my container...

Thanks a lot for your help !

Hi, I guess its because you have to map Traefik to Bitwarden's internal ports (80 and 3012). I'm also unsure why you would open ports directly if you are using a reverse proxy.

Hi Dennis,

Thank you very much ! It's work !
I am a beginner with Traefik and also Docker... You just made me understand a new notion :)
I did not understand that the redirection must be done on the internal port of the docker and not on the redirected port.

Thanks again !

Hi @Daams13, sorry for replying to a closed issue here. But I have the exact same issue.

Can you tell me how you fixed this Bad Gateway problem?
