Collabora-Office unreachable after update from 6.2 to 6.4 - SOLVED

Hallo, all,

I’m running Nextcloud 19.0.3 on a Debian 9 web server successfully with Collabora-Office but since an update of Collabora-Office from Version 6.2 to version 6.4 on 24th of September, the connection to Collabora fails.
I installed my own Collabora Online server and everything was fine since this update.

In my logs I find the following errors, if I stop loolwsd.service and start it again:

The service loolwsd seems to run, but neither I can configure the Collabora Online Server in Nextcloud configfuration backend, nor I can get a connection to the online available admin tools of the service as I formerly could.

I tried to reinstall, but the problem persists.

Does anybody has any similar experiences and can give me a hint, how to solve my problem?

Thank you in advance!

Ralf

The problem was solved by an update, which I could get today.

Everything seems run fine again.

Greatings, Ralf
