Remote application session getting terminated

Hi All,

We have onboarded the Remote Web application in our Beyondtrust Password safe instance.  The launch of application is successful and user can access the application without any issues.

However whenever user tries to modify the size of browser window, session terminates with below error 

Has anyone encountered this issue previously ? If yes, can anyone please suggest how the issue was resolved ?

Awaiting response. Thanks in advance .

Regards,

Immi
