laravel horizon puts everything in pending - laravel

Question

I was running horizon with supervisor but then killed supervisor and am just running
php artisan horizon
I have 2 queues and separate supervisors for both. Here is the horizon config.
'defaults' => [
'logger' => [
'connection' => 'redis',
'queue' => [env('QUEUE_DEFAULT', '{default}')],
'balance' => 'simple',
'maxProcesses' => 1,
'memory' => 128,
'tries' => 2,
'timeout' => 30,
'nice' => 0,
],
'scheduler' => [
'connection' => 'redis',
'queue' => [env('QUEUE_SCHEDULE', '{schedule}')],
'balance' => 'simple',
'maxProcesses' => 1,
'memory' => 128,
'tries' => 3,
'timeout' => 30,
'nice' => 1,
],
],
'environments' => [
'production' => [
'logger' => [
'maxProcesses' => 3,
'balanceMaxShift' => 1,
'balanceCooldown' => 3,
'memory' => 256
],
'scheduler' => [
'maxProcesses' => 2,
'balanceMaxShift' => 1,
'balanceCooldown' => 3,
'memory' => 256
],
],
'develop' => [
'logger' => [
'maxProcesses' => 2,
'balanceMaxShift' => 1,
'balanceCooldown' => 3
],
'scheduler' => [
'maxProcesses' => 2,
'balanceMaxShift' => 1,
'balanceCooldown' => 3
],
],
'local' => [
'logger' => [
'maxProcesses' => 2,
],
'scheduler' => [
'maxProcesses' => 3,
],
],
],
When testing on develop env, horizon randomly processes one job on the default queue. default queue holds the jobs pushed by a queued event listener, which does nothing but writes logs to file.
It randomly works and processes a job and then everything goes into pending in horizon and never processed.
If I run
php aritsan horizon:terminate
and then restart horizon, sometimes it processes 1 job and then again starts placing everything in pending.
Here is my queue and database config for redis.
'redis' => [
'driver' => 'redis',
'connection' => 'default',
'queue' => env('QUEUE_DEFAULT', '{default}'),
'retry_after' => 900,
'block_for' => null,
],
DB:
'redis' => [
'cluster' => true,
'client' => env('REDIS_CLIENT', 'predis'),
'options' => [
'cluster' => env('REDIS_CLUSTER', 'redis'),
],
'clusters' => [
'default' => [
[
'scheme' => env('REDIS_SCHEME', 'tcp'),
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => env('REDIS_DATABASE', 1),
],
],
