“Please make sure your credentials are valid”, got this error while activating Katalon Studio

Hello Team,

I have activated the Katalon studio (account is verified through email, TestOps page) but I am getting this error “Please make sure your credentials are valid” while working.
Given the same credentials again and click on activate button multiple times, then the message disappeared after giving me the message successfully activated. But after some time the activation windows appears.
I can login to the web but not in Katalon Studio.

Please help me on this.
