Can’t Use Same Port in New Data Input (Modular Input)
Symptom: After deleting an existing configured data input (modular input), you can’t create a new modular input on the same port.
Cause: The port number is still in the Data Input TCP ports list.
Fix: Remove the port from the Data Input “TCP” ports list before you try to use the same port again. This enables you to reuse the port which was configured in the previous data input (modular input).
