I can confirm that your workaround solved that issue, thanks for your quick reaction, now I will update Collabora in production!

I was able to reproduce this issue with Nextcloud.
This is not a Collabora issue but a Nextcloud issue .
When using the same Collabora app from Cubby it works without any issue.

I also noticed the issue persists when restoring the previous version of Collabora.
So this is some caching issue from Nextcloud and the Office app from Nextcloud.

Found a quick hotfix as well.
When updating or restoring Collabora, Nextcloud throws the Unauthorised WOPI host. Please try again later and report to your administrator if the issue persists. error.
But when you go into the admin settings of Nextcloud, go into the Office section, check the checkbox Disable certificate verification (insecure) and Save uncheck and Save again, the issue is resolved.

Can you please attempt this as well?
