OnlyOffice isn't working in Nextcloud

Truenas Scale Version: 25.10.6 - Goldeye
Version Nextcloud Hub 26 Spring (34.0.3)
Onlyoffice App Version: 9.4.0, Version: 1.2.32

Hello, everyone.

For some strange reason, OnlyOffice has stopped working in Nextcloud. I tried to open a document just now, and this is what happened. Has anyone else encountered this issue?

Thanks for your help.

9.4.0 is strange version number to have with Nextcloud v34, at least if you’re referring to the connector app:
