I had the problem that new nextcloud clients cannot connect to my nextcloud server (snap, version 14) (the client login loop problem. In a forum thread I read that I had to set overwriteprotocol.
So I executed the following command:

snap run nextcloud.occ config:system:set overwriteprotocol ‘https’

This returned with:

System config value overwriteprotocol => https set to empty string

And now any command I run will throw an error:

snap run nextcloud.occ config:system:get overwriteprotocol

An unhandled exception has been thrown:

I tried to update to version 15
snap refresh nextcloud --channel=latest/stable
Which seemingly went fine, but still no nextcloud running.

What did I do wrong and how can I fix this.
My whole server is down.

This doesn’t have anything to do with the snap-- you’re not using occ correctly (and occ doesn’t sanity check values, it seems). You should have run:

$ sudo nextcloud.occ config:system:set overwriteprotocol --value 'https'

See sudo nextcloud.occ config:system:set --help for the details, but to unblock you, do this:

Open up your config (as root) in your favorite editor, the file is located at /var/snap/nextcloud/current/nextcloud/config/config.php. Find the overwriteprotocol and you’ll notice that it’s an array instead of a string:

// ...
'overwriteprotocol' =>
  array (
    'https' => '',
  ),
// ...

Change those lines to look like this:

// ...
'overwriteprotocol' => 'https',
// ...

Sorry, didn’t read the question properly. :roll_eyes:

Thank you for the detailed answer. It helped a lot :slight_smile:

I had an inkling on what would be wrong but I could not find the correct file to edit (nextcloud is the only snap I actually use).
