Connection to vSphere VMs stops working after a while

[HanSooloo]

Started happening with Fusion 11.5 and my vSphere 6.7 installation.  I don't recall having similar problems with earlier version.

Very easy to reproduce:

1. Connect to VCSA server using Fusion.
2. Connect to any VM by double-clicking on its name.
3. The window opens with the selected VM's screen, e.g., a Windows 10 machine.
4. Wait a few minutes (haven't timed it, but something around 5 mins or so).

Observed results:

1. Coming back to my Mac, click inside the VM window.
2. Screen is completely unresponsive.
3. Double-clicking on VM name inside the VCSA VM list yields same result.
4. Right-click on VCSA server name, and click "Refresh".
5. Double-click on VM, then live connection to VM is restored.

Expected results:

1. Connection to VM stays alive with no interruption.

It is a known issue in Fusion 11.5...

There is a workaround in the thread below

I'm not sure if it will work in your environment, but still worth a try.
