Nextcloud 13.0.3 and Collabra CODE


try to run next cloud 13.0.3 with Collabra CODE last version with Collabra Plugin 2.0.8 - Does not work.

It says that the document type is not known, or not supported:

The complete german error message is:

“Das Laden des Dokuments ist fehlgeschlagen. Bitte vergewissern Sie sich, dass der Dateityp unterstützt und die Datei nicht defekt ist, und versuchen Sie es dann erneut.”

Can anyone help me out?

With best regards


I had this problem as well. Had to restart the docker service (something about networking).

systemctl restart docker(d)

Dear Mike,

I’ve already done the docker restart and also the restart of the hole system.

the docker start is initiated via:

docker run -t -d -p -e ‘domain=domain\.com’ --restart always --cap-add MKNOD collabora/code

any further ideas?



does anyone have an idea how to proceed?

With best regards


I have this problem as well but with NC 13.0.2 - Just curious… do you have encryption enabled?
