Katalon authentication problem in TeamCity

Hello, my situation:

jenkins installed on win7 machine as “windows service”,
katalon studio installed on the same machine (activated via “offline activation”).

The problem is, when I run my test in jenkins, I get “Katalon is not activated” message. Adding username and password to cmd won’t help, I get “Network error! Cannot execute activation.” error. I suppose this is because my company blocks many ports, in addition I’m not able to configure proxy.

Do you have any suggestion how to solve this problem? On katalon or jenkins side.

ps.

if I start jenkins not in “windows service mode”, but just run java -jar jenkins.war all is fine. But jenkins on that machine must work as windows service and I’m not allowed to change it…
