Hello AHorv5

Thank you for posting in the Intel Community.

What are the Intel Unite® versions installed on the server, HUB, and clients?

Was this environment working properly at some point? Was there any change in the environment prior to this error?

Can you attach the client's log file on the thread? 

You can find steps to get the logs on the following links:
