Hi everyone,

I try to setup Vaultwarden on my unRAID as container using NGINX Reverse Proxy on my OPNsense Firewall (Different machine).

It works with my current proxy setting, when I use "/" as base path. But when I change my path to "/bitwarden/asgard" or something else and change the domain on the container itself to look like: -e 'DOMAIN'='http://localhost/bitwarden/asgard' It doesn't work. I get the 404.
I can leave the Domain on the Container with "http://localhost/bitwarden/asgard" and change the Proxy config to "/" again, it works ...
Seems like the base path inside the container is not working? When I look at the read-only config in admin section it looks like:
Domain Origin: http://localhost
Domain Path: Default: /bitwarden/asgard
I used this config as an example: https://github.com/dani-garcia/vaultwarden/wiki/Proxy-examples

Any idea why subpath is not working?
