I have the client 9.1.7 connects great but within seconds the server does not ping me

[LeNNe]

The desktop pulse connects me correctly and ping the device and the shared folders, 
but when I try to open a network folder that I have access to, it stops pinging me even
 though the application is still connected.  I have kaspersky endpoint security for windows version 11.3.0.773. 
But I think it is not an antivirus problem because I uninstall it and it 
still doesn't work. Can you help me?
