The token field is empty. That's the field ncpa uses for authentication. Can I give you some good advice? You'd be doing yourself a huge favor if you dig into the documentation on their website. For just about anything you need to do, there's plenty of info.

Did adding the token resolve your issue?

Are you able to connect to the NCPA client with a browser? i.e., go to https://ip address:5693/?

Ignore the ssl warning that will appear, and use your token to log in.
Please let us know if you have any other questions or concerns.

Hello,

on my side, it was a firewall dropping the flow, even if i catched it using telnet.
