I did a fresh install of the latest UCS version, installed Nextcloud, added my domain to the trusted domains, installed Collabora, activated the Collabora in NC and tried Collabora, it didn’t work.
I tried to install it on a more mature system, which uses Let’s encrypt, same issue.
The problem is discussed in this thread, too:
I created a new thread, so put it in Apps and App Center and also, because we must miss something fundamental.
So what additional steps must be taken, that Collabora works, or how can we debug it? (I suspect there is some issue with some certificates, but I don’t know what to do.)
Can I access Collabora directly without the login to NC?
