I have installed CDSW in my cluster and created a project. But while launching the session I see the following error.

I'm adding the details of 'cdsw status' here,
[root@edge ~]# cdsw status

@sandipkumar

This issue is probably with wildcard DNS and SSL . From the provided output I could see that you are not using SSL. So, it is worth to check wild card DNS on your local machine and cdsw nodes I have give below the URL for your reference. Please take a look.
