Hi All,

I tried to create a remote session from windows desktop but I report so many issues

Kobiton 7.2.1  
Java 13.0.2

My configuration is well but I have same error when I run my script.  
Error message:

> com.kms.katalon.core.exception.StepFailedException: Unable to start app at: ‘kobiton-store:XXXX’ (Root cause: org.openqa.selenium.SessionNotCreatedException: Unable to create a new remote session. Please check the server log for more details. Original error: Unauthorized

I don’t understand why unauthorized however my Katalon is connected to Kobiton.  
Thks !
