public_wopi_url is automatically detected incorrectly and cannot be set manually.

Describe the bug
Url is automatically detected incorrectly and cannot be set manually.

To Reproduce

# Check boths URLs
php occ config:app:get richdocuments wopi_url
php occ config:app:get richdocuments public_wopi_url

# Set Url
php occ config:app:set richdocuments public_wopi_url --value=https:\/\/cloud-test.borntoberoot.net\/custom_apps\/richdocumentscode\/proxy.php?req=

# Check URL again (it's correct)
php occ config:app:get richdocuments public_wopi_url

# Activate config
php occ richdocuments:activate-config

# Check again (it's not correct, again)
php occ config:app:get richdocuments public_wopi_url

Expected behavior
URL is set correct after this.

Screenshots
URL is wrong

Server details

Latest docker-image: nextcloud:23-apache
Latest collabora app via AppStore: richdocuments, richdocumentscode (x86/x64)

@juliushaertl Any idea how to change the url or detect the proxy correct?

I setup the collabora code server via docker and had to set the variable server_name to my external domain of collabora:

  # Collabora office
  office:
    image: collabora/code:latest
    container_name: nextcloud_${ID}_office
    restart: unless-stopped
    networks:
      - traefik_proxy
    environment:
      - domain=cloud.example.com
      - username=admin
      - password=123456
      - server_name=office.example.com
      - "extra_params=--o:ssl.enable=false --o:ssl.termination=true"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.nextcloud_${ID}_office.rule=Host(`office.internal.example.com`)"
      - "traefik.http.routers.nextcloud_${ID}_office.entrypoints=websecure"
      - "traefik.http.routers.nextcloud_${ID}_office.tls.certresolver=dns"
      - "traefik.http.routers.nextcloud_${ID}_office.tls=true"
      - "traefik.http.services.nextcloud_${ID}_office.loadbalancer.server.port=9980"
      - "traefik.docker.network=traefik_proxy"

Before setting server_name the public_wopi_url was automaticaly set to office.internal.example.com. Since this domain is not reachable from the internet, the documents failed to load.

Would be great if we can set/override the server_name for the build in code server.

My problem is solved for my instances. Feel free to close this issue if it is no longer relevant for you (e.g. setting the server name for the build in server).

I think setting it manually might still be useful in some setups, so let's keep this as an enhancement request.

[podhorsky-ksj]

I think, this should be bug. I have similar issue. In my case I need to access collabora with http, not https. Set public_wopi_url is not working and I cannot use the workaround, because used ip address/host is correct. I only need to change https to http.

@podhorsky-ksj If you don't want https for whatever reason and you are using the docker container you can try to pass this environment variable to the container: extra_params=--o:ssl.enable=false. or if you're not using docker you can edit the coolwsd.xml file for your server to disable ssl. but that doesn't seem entirely relevant to this issue

[juliusknorr]

You can also manually verify that http://your.collabora.server.com/hosting/discovery returns the proper URL with plain HTTP by requesting that address and verifying the urls in the output
