Watch tower not working ???

[toome123]

Hello, i want to enable Watch tower client to secure my node, and i see that in advanced setting there is Watch tower options available. When i enable it, and set it up i wanted to verify that everything is working properly, so i execute command
lncli wtclient towers

The output is shows:
"active_session_candidate": false, "num_sessions": 0
And i thing something is not right.
Is it needed to do something additional to make this work ? Like set some 9911 port config somewhere or ??
Please assist me to find what the issue is..
