Hesk 3.4.1 not functioning on frontend with PHP 8.1. Backend no problem.
Message displayed on frontend:
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
When PHP version switched to 8.0 there is no problem.
Is Hesk 3.4.1 compatible with PHP 8.1?

Hesk 3.4.1 is fully compatible with PHP 8.1; in fact, the development server is also running 8.1

The "Service Unavailable" is not generated by Hesk, but by your server. You will need to check your server error logs to see what is going on.

Hard to say what is going on without having any of the requested information.

Are you able to share your phpinfo?
URL of your help desk?

I am using FastCGI PHP 8.1.
I have 4 sites that use HESK, each of them with their own third-party modifications
The flight is normal, everything works, absolutely no problems.

The only issue I have where I get an HTTP ERROR 500 error is when I enable ticket formatting (HTML).
But I uploaded this HESK (full backup) to another VPS hosting with another Linux and this error problem is gone.

It will be necessary to deal with it and understand which server setting caused this problem.

I am afraid I can't be of help here without access to the help desk.

Maybe you can use this trick to find the line in your index.php file that is causing the error:
