Login Failed error message in Webi Rich Client

Hi ,

When I try to login in to Webi Rich client , I get the error message "Login Failed". However, a session seems to have been created on the server in CMC. I am able to connect to another server using same Webi Rich Client. Other BO tools like Universe Designer also work fine. I am on BO XI 3.1.

Please let me know if anyone has faced this issue.

Thanks,
