Does not expose behind a reverse proxy

[PovilasID]

Hey,

I failed testing running librum server behind traefik. Traefik is fairly common reverse proxy to expose services. I am getting 404 then I visit exposed 5000 port. I am also getting some warning:

Running in selfhosted mode, skipping AzureKeyVault configuration

Not sure if those warnings are relevant.

Here is my traefik config in docker. You do not need to know how traefik works it is just to confirm that I am using right port and that I am exposing it with SSL enabled.

    labels:
      - 'traefik.enable=true'
      - 'traefik.http.routers.librum.rule=Host(`librum.mydomain.com`)'
      - 'traefik.http.routers.librum.entrypoints=https'
      - 'traefik.http.routers.librum.tls.certresolver=letsencrypt'
      - 'traefik.http.routers.librum.service=librum-service'
      - 'traefik.http.services.librum-service.loadbalancer.server.port=5000'  

Traefik does not need you to have SSL or anything... just expose it raw let me handle SSL certs myself.

As an aside: Why is there Azure vault config for your domain in selfhosted config? https://github.com/Librum-Reader/Librum-Server/blob/e7f95caea2fdbf7823babe47355b6f770d24bd3d/appsettings.json#L16

This is a rest API, thus a 404 is expected when accessing no specific endpoint. Have you just tried reaching out to the main domain of Librum, or do the individual endpoints lead to 404 errors for you? #23 has added a message to avoid the 404 confusion.
