I am no longer able to access my documents from the browser on my home server. I have tried the following:

1. Uninstalled and reinstalled Nextcloud Office App
2. Uninstalled and reinstalled Collabora Built-In CODE (ARM64) App
3. Renewed SSL cert
4. Updated Nextcloud instance
5. Updated and upgraded Raspberry Pi OS
6. Updated and upgraded PHP
7. Set PHP 8.0 or higher as default
8. Tested the removal of IP addresses from WOPI allow list setting in the browser

Not sure what more I can do with this, but it appears to be a bug with the latest update of Nextcloud office.
