Hi,

I'm having a hard time with the netskope client on Linux. This is a WSL2 installation, and a netskope agent is running on the windows host. But the windows agent status has no influence on the behavior of the guest linux one.

Very often, the nsclient config outputs a normal status with tunnel up, and private access enabled. Unfortunately the show-pa show this :
 

 $ nsclient show-pa
start process....


Status: Connected (User Tunnel)
        Sent: 0 bytes
        Received: 78646 bytes

and the nsdebuglog.log is spammen with this kind of errors :

This is a very unstable behavior as from time to time, doing mothing, the private apps are accessible again.

Do you any idea guys how to tackle this ?
