Multiple client connections to the token server from the same client system

We currently run Gurobi 951 on a dedicated Windows Server 2019 Virtual Machine. This is our token server. Our floating license is for 3 concurrent connections. 

When the client system has an error that affects the Gurobi process, shouldn't the Gurobi client / server connection be closed? Or does the Gurobi client / server connection remain active when Python ends up with an error? After resetting the Python kernel, the concurrent connection counter on the Gurobi token shows that 3 concurrent connections can be made again. 

I would like to know how to prevent multiple client connections from the same system.

 This is quite new territory for me. I hope I am making sense.

Thanks in advance.

  it is possible to create multiple connections to the token server from the same machine, for example, if different optimization runs are started from the same machine, each one will use a token and create a connection to the token server, this is the default behavior.
