Describe your issue

Hi.
After the last Nextcloud update, Nextcloud Office (Collabora) is not able to establish a connection to my Collabora Online Server anymore.
Is there anybody who can help me?

Something related to collabora in nextcloud>admin>logging?
You can also check, via yunohost webadmin, collabora logs: tools>services>coolwsd.

Thanks for your reaction.

The protocol of Nextcloud is 25,5 MB big.
Here is the protocol of the service coolwsd:

Thank you for help.

Can you share the output of

df -h
journalctl -k | grep -iE 'oom|killed'

?

Hello.

This ist the output of df -h:

There is no output of journalctl -k | grep -iE ‘oom|killed’.

Same with me. “Use your own server” is greyed out. Previously I used the Yunohost Collabora server which I have removed now. I wanted to use an external instance, but I cannot change the server address

journalctl -k | grep -iE ‘oom|killed’ gives no output

I see this error in the nextcloud logs

Maybe trying to uninstall and reinstall the nextcloud office app.

tried it, but did not help, I cannot edit anything

Please share logs and error messages.
I guess you will need to declare your nextcloud server as WOPI host in your collabora server configuration.

Try restarting coolwsd service.

tail -n 100 /var/log/nextcloud/nextcloud.log

And collabora service log after restarting.
