Problem

Seen on vSphere:

Error Host {hostname} could not reach isolation address:none specified.

Solution

1. In my case the host did NOT have a default gateway, (this had occurred because the subnet mask of the server had been entered incorrectly when the server was built. So the default gateway appeared to be on a different network).

2. With the offending host selected, Configuration > DNS and Routing > Properties > Routing > Put in the correct default gateway > OK.
