J-Link Remote Server Unknown EMU command #28

Hello,

I'm using J-Link tools version 6.32c and trying to test the remote server function with a USB J-Link. I run remote server on one Windows 10 machine. I then launch J-Link Commander on the second Windows 10 machine within the same LAN.

After executing a connect command I eventually receive a message box on Remote Server stating "Unknown EMU command #28 received. Discontinuing parsing of communication".

Thank you for your help,
Jim

Below is a capture of the Commander console and error.
