I'm a newbie to TREX. I was trying to connect remotely through the PYTHON APIs. I ended up with the below error. The TREX version used by me is V2.2.0. Could someone help me find out if I have the correct version installed ? Is the below error due to any incompatibility.

client - side logs:

The port is not the right one. just remove it (default is 4501)

STLClient(username = "trex",server = "172.26.156.57", sync_port = 4507

Connecting to RPC server on csi-kiwi-02:4501
