Gitlab Runner - Use Token multiple times?

Hello Guys,

we have very heavy builds to execute on azure machines.
I am currently trying to build terraform IaC code that starts 4 virtual machines parallel and on every machine a build gets executed.

My only problem is now registering the runners. In the Documentation they said 1 created runner authentication token can registrate multiple hosts/runners with the token/config file. Plan and operate a fleet of shared runners | GitLab
But it is not working I always get the information “PANIC: Failed to verify the runner.”. Even the old, deprecated token is not working with multiple runners on multiple hosts anymore…
Only creating a fresh Token and add this specific token to the cloud-init works. For 1 machine.

Any suggestions or do understand something wrong? Do I need now to create those tokens automatically with curl… since everything changed?
