Setup behind reverse proxy

[pebalk]

Hi and sorry for bothering you brother

I still could not find the root cause of the issue of my docker setup.
I've checked that reverse proxy (traefik in particular) has set Hostname, Host and X-Forwarded-Host correctly with whoami container. However even on fresh setup on Welcome page {{ .host }} in the head.html title is null and looks like:

<title>-Welcome</title>

Any suggestion how to fix that? What additional info should I pass to the x-ui server so it could get my hostname?

PS. Just to confirm hostname is set via docker and setup runs smoothly if access directly excluding reverse proxy.

Is there any possibility to add to Panel Settings - General tab a new field Reverse Proxy URI like in Panel Settings - Subscription tab now?

What should we do for you ?
The question is not clear! Traefik proxy should send the host header to backend in this case.
