Application not getting launched using functional account

Hi All

I have onboarded multiple applications in Beyondtrust password. We are using cloud version of password safe.  All the thick client application like winscp, sql developer,toad etc are not getting launched using functional account. Web application using same function account gets launched. 

I am able to access the application from session host from cmd. however from password safe it is failing. All ports are open and Functional account test is also passing 

Does anyone has any idea whats the problem.. any pointers will surely help.

Regards
