Description:
Collabora Online + Nextcloud Integration – Status & Outstanding Issue Environment Server: Dedicated Linux server (Plesk, EL9) Reverse proxy: Plesk-managed nginx (in front of Apache) Nextcloud: Self-hosted instance (HTTPS) Collabora: External Collabora Online server (Docker-based) Proxy model: nginx reverse proxy CDN / WAF: Disabled during testing SSL: Terminated at nginx (Collabora running without internal SSL) What Has Been Completed (and Verified) 1. Collabora container deployment Collabora Online is running in Docker Exposed internally on port 9980 Container starts cleanly and remains healthy Verified via direct local HTTP request: /hosting/discovery → HTTP 200 OK 2. nginx reverse proxy configuration nginx successfully proxies Collabora endpoints: /hosting/discovery /cool /browser WebSocket upgrades are enabled and functioning Verified externally over HTTPS: /hosting/discovery → HTTP 200 OK 3. SSL / proxy alignment SSL is terminated at nginx Collabora started with: SSL disabled internally SSL termination enabled This matches the reverse proxy architecture No TLS or certificate errors observed 4. CDN / firewall eliminated as a factor CDN/WAF fully disabled during testing Requests go directly from client → nginx → Collabora No CDN headers or interference present 5. Nextcloud Office configuration “Use your own server” selected External Collabora URL configured (HTTPS) Built-in CODE server disabled Demo server not used Admin UI reports Collabora as reachable 6. WOPI allow list configuration WOPI allow list configured in Nextcloud No token-based authentication configured Certificate verification left enabled (public certificate in use) 7. nginx validation nginx configuration validates successfully Reload performed via Plesk tooling No nginx syntax or runtime errors Current Behaviour (What Works) Collabora service starts normally Reverse proxy works correctly Discovery XML loads both: Internally (direct to port 9980) Externally (via HTTPS proxy) WebSocket connections establish successfully No networking, firewall, or SSL failures observed Current Issue (Still Failing) Error shown in Nextcloud UI Document loading failed Unauthorised WOPI host. Interpretation of the Error Collabora is rejecting the WOPI request Rejection happens after discovery and WebSocket setup This indicates a WOPI host authorisation failure, not a connectivity issue Likely Root Cause (High Confidence) The Collabora domain allowlist regex does not exactly match the WOPI host string generated by Nextcloud. Typical causes: Host includes an explicit port (e.g. :443) Regex not anchored (^ / $) Multiple valid hostnames not fully accounted for This is a known and common Collabora failure mode. Evidence Supporting This Conclusion Network path is fully functional SSL termination is correct Discovery and WebSockets work Error is specific to WOPI authorisation CDN/WAF is disabled Logs show normal Collabora startup and request handling up to WOPI validation Trying to get AI apps setup and working, trying to do this broke the Next docs.
