Cannot pilot my online experiment from dashboard

Windows 10
v2020.1.3.
Chrome

Description of the problem: I have pilot token error when I want to pilot my experiment from Dashboard:
error3

I have checked similar topics however none of the suggestions helped me. Until 2 days ago I was able to pilot experiment (the one also I am trying to run now) through Dashboard → Pilot.

I thought, maybe it is caused because of my IP adress {“ip”:“88.230.229.245”}?
What can be the problem?

Many thanks in advance!
