Seeking assistance setting up traefik with wireguard server

I'm hoping someone can help me figure out what I'm doing wrong.

I have a VM on my local network that has Traefik, 2 apps (whomai and myapp), and wireguard in server mode (let's call this VM "server"). I have another VM on the same network with Traefik and wireguard in client mode (let's call this VM "client").

both VMs can can ping each other using their VPN IP addresses
wireguard successfully handshakes
I have myapp.mydomain.com as a host override on my router so every computer in my house points it to "client"
when I run curl -L --header 'Host: myapp.mydomain.com' from the myapp container it successfully returns the myapp page.

But when I browse to http://myapp.mydomain.com I get "Internal Server Error", yet nothing appears in the docker logs for any app (neither traefik container, neither wireguard container, nor the myapp container).

Any suggestions/assistance would be appreciated!

Just a few thoughts:

Did you enable access logs in Traefik as well as setting global log level to debug? This usually gives a lot more info about whats going on
Are the containers using the same docker network or host network, so they can reach each other?

Thanks for helping, @deergon@lemmy.world.

Both traefik containers (on the "server" and "client" VMs) and the wireguard server container were built with TRAEFIK_NETWORK_MODE=host. The VMs can ping each other and the Wireguard containers can ping each other.

Both traefik containers were built with TRAEFIK_LOG_LEVEL=warn but I changed them both to TRAEFIK_LOG_LEVEL=info just now. There's a tad more info in the logs, but nothing that seems pertinent.

How about the Traefik access logs (separate from the main log), do they reveal anything?

From traefik's access.log:

All I can tell from this is that there is a DownstreatStatus of 500. I don't know what that means.

Have you tried accessing your service url from inside the Traefik container? Eg. wget https://10.13.16.1? Also you seem to be accessing the service url with https, which usually requires insecureSkipVerify=true. Otherwise you might get http-500 error downstream.
