Hey,
since the update to NC 19 I'm unable to use twofactor_gateway. I'm using Signal as a backend and configured the local gateway (running on localhost).
This is the eror message:

I'm using the latest version of the app, 0.16.

cool thank you @ChristophWurst, setting 'allow_local_remote_servers' => true, into config.php solved the issue for me :)
