Integration of Collabora with OpenCloud on TrueNAS Scale

Installation & Configuration
1

Hello, everyone. I need help integrating Collabora with OpenCloud. I installed OpenCloud and Collabora from the app store on my TrueNAS Scale, but Collabora isn’t showing up in OpenCloud. Has anyone else installed and configured this integration on a TrueNAS Scale?

Hello. I installed both Collabora and Opencloud via Discover Apps. I’m attaching screenshots of the settings

ERR #30: Looks like SSL/TLS traffic on plain http port| wsd/ClientRequestDispatcher.cpp:753

This is an error I found in the Collabora logs

hi @mulled it looks like mismatch of SSL links

OpenCloud is sending HTTPS traffic to a Collabora port that’s expecting plain HTTP.

In your OpenCloud configuration, the Collabora URL is set to https://192.168.110.53:9980, but your Collabora instance isn’t configured with SSL/TLS — it’s listening for plain HTTP on that port. When the HTTPS request hits the plain HTTP listener, Collabora rejects it with that ERR #30.

The fix: In the OpenCloud configuration, change the Collabora URL from https://192.168.110.53:9980 to http://192.168.110.53:9980.

A couple of additional things to check once you make that change:

Since your OpenCloud application URL uses HTTPS (https://opencloud.finger.su) but Collabora would be reached over plain HTTP, some browsers may block the connection as “mixed content.” If that happens, you have two options: either set up a reverse proxy that terminates SSL for Collabora too (giving it a proper HTTPS endpoint), or access OpenCloud itself over HTTP while testing to confirm the integration works at all before layering in SSL.

Also make sure that port 9980 is actually reachable from the OpenCloud container — since both are TrueNAS apps, they should be on the same network, but it’s worth confirming with a quick connectivity test from the OpenCloud shell (curl http://192.168.110.53:9980).
