Workaround:

Modify Two registry:

Hkey_local_machine\system\currentcontrolset\services\tcpip\parameters\maxuserport if not, manually create a DWord (32-bit) "Value data" Change to a decimal 65534 or a value that is considered appropriate.

This value represents the maximum number of ports used by the user and defaults to 5000.

Hkey_local_machine\system\currentcontrolset\services\tcpip\parameters\tcptimedwaitdelay if not, manually create a DWord (32-bit) " Value data "to decimal 30 or the value you think is appropriate.

This value indicates how long a closed port waits and can be reused, with a default of 120 seconds, or 2 minutes before it can be reused.
