I have a Nextcloud and a Collabora docker installation. Both are behind a Traefik reverse proxy but on the same network (172.20.0.0/16). I can’t get the allow list for WOPI requests to work. I found several other posts with this issue but their solutions wouldn’t work for me.
First, some people just put in the docker network range. That didn’t work for me. Collabora wouldn’t load. Do Nextcloud and Collabora need to be connected directly in that case? Meaning not via “https://collabora.mydomain.com” but via “collabora-container-name:9980”?
Secondly, others put in their public IP. That does work and Collabora loads fine, but because I have a dynamic IP that is not a viable solution.
Another problem is that all solutions use NGINX reverse proxy which I have no experience in.
