We’ve exactly the same problem since upgrading our CODE server to version 184.108.40.206-49 (from 220.127.116.11-48) which brings LOOLWSD HTTP Server 6.4.13. I don’t see any problems neither in the Nextcloud nor in the CollaboraOnline server logs. Only the message about the undefined Cursor is shown in the browser console.
We are running NC 20.0.12 and the Collabora Online App 3.8.6.
What did you change? Did you update your Collabora Online server (like we did before we’ve run into the problem)? Which version of the Collabora Online App do you use in Nextcloud? Which version of Nextcloud do you run?
I have read you’re answers and the links embeded but I think they’re not appropriate to my configuration.
I’ve got NextCloud 18.104.22.168 and Collabora is installed from the Application menu and, at this time, Collabora is in version 4.2.3 and CODE in 6.4.1303
I suppose it’s the latest version ?
Do I have to install CODE following this guide https://www.collaboraoffice.com/code/linux-packages/ ?
