- Goto Apps > Your Apps
- Locate «Collabora Online - Built-in CODE Server»
- Click the Button [Update to 22.5.702]
- After 2-3 seconds there is an error message «An error occurred during the request. Unable to proceed.»
No further actions are possible since there is a message «Maintenance mode».
I need to open config.php and change
‘maintenance’ => true,
‘maintenance’ => false,
Then Nextcloud is accessible again, but the app is not updateable.
