Requests pending randomly for 90 seconds

Hello, I'm relativly new to Laravel and have problem with my new Laravel application. There are often requests that are pending for 90 seconds. Most of the time the requests need only milliseconds and it doesnt depend on the request itself.

My application was installed directly on my server with SSH and Composer. Then I hoped to fix it by installing it with the Laravel Plesk extention.

I tried setting the app_env to production or local, setting the retry_after in queue.php to 30, but no difference. In the logs I cant see a problem that causes this behavior.

If I could see more in the log what causes the problem, I could maybe fix it by myself. But I dont know how to get more information. Can anyone help me finding the problem?

This is my current configuration:

Laravel Version ..................................................... 9.41.0 PHP Version ......................................................... 8.1.18 Composer Version ..................................................... 2.3.0 Environment .......................................................... local Debug Mode .........................................................
