sudo -u www-data php /var/www/nextcloud/occ notify_push:self-test

✓ redis is configured
✓ push server is receiving redis messages
✓ push server can load mount info from database
✓ push server can connect to the Nextcloud server
✓ push server is a trusted proxy
✓ push server is running the same version as the app

Push service is running, port 127.0.0.1:7867 is open.

I hope someone can help.

thanks
