Can RAP work with muximux?

[jamiesmith]

I am trying to stand muximux (linuxserver/muximux) up behind this, but I can only get 503 Service Temporarily Unavailable.

I have a wildcard dns set up pointing to the IP of my homelab rancher server, call it *.lab.foo.com

I have tried different combinations of rap.https_method and expose to no avail. I had hopes for:

docker run --detach \
    --label rap.https_method=nohttps  \
    --label ras.host=muximux.lab.foo.com  \
    --label rap.port=80 \
    --name=muximux \
    --restart=always \
    --volume /docker/containersmuximux/config:/config \
    --env PGID=1100  \
    --env PUID=1100 \
    --expose 80 \
    linuxserver/muximux    

But it also yielded a 503.

Inspecting a running muximux container shows that it exposes both 80 & 443:

        "Config": {
            ...
            "ExposedPorts": {
                "443/tcp": {},
                "80/tcp": {}
            },
            ...

Any tips you can give to get this to work would be appreciated, Thanks
