Hii @amberleaf
Add the problematic IP (or better, your Docker subnet or 0.0.0.0/0 for testing) to the “Allow list for WOPI requests” in Nextcloud Office settings, then restart your Collabora container. This fixes the WOPI request denied error caused by unexpected IPs.[
For setup guides and fixes, check existing forum discussions:
Collabora with nextcloud and traefik on docker.
