Unable to login using new FitNesse version 17.4.1

I am not able to login into Appian with latest FitNesse version 17.4.1.

!| script |com.appiancorp.ps.automatedtest.fixture.TempoFixture|
|setup with |CHROME |browser |
|set appian url to |XYZ.com/.../login.jsp|
|set appian version to|17.4 |
|set appian locale to |en_GB |
***!
!*** Login to Tempo and go to Records
!| script |
|login with username|${USERNAME}|
***!

Browser gets opened up however when suite reaches login option URL gets changed automatically to logout. 'XYZ.com/.../logout' and there is no login button after this.
