horizon: Horizon dies after few seconds

Hey, I am trying to set up the local environment. I can see horizon dashboard with Inactive status. When I am running php artisan horizon the status changes to Active for a second and then changes back to Inactive again. I tried using supervisor to run horizon but the same problem. From the supervisor logs I can see that it’s running for a second, then restarting and starting again all the time. Is there any way to debug horizon and check why is it dying? I tried running php artisan horizon -vvv but every time the output is the same: Horizon started successfully. and then terminating the process. I can also confirm the queue is working fine when I run it using php artisan horizon:work.

Environment details: Using Apache as a server on Ubuntu 16.04. Laravel version: 5.6.14 PHP version: 7.2 Redis server version: 4.0.11 Horizon version: 1.3

Any suggestions?
