Well, if you use ip-address (and it is correct) and a reboot of the Host solves the problem ... this feels like Windows 10 networking instability. 

Not really consistent with this, but you may have some anti-virus software, which works as firewalling the system. Not sure, why its behavior changes when you reboot the Host. If not - well, one of those Windows 10 problems, I gather. There are regressions in Windows .dll's.

If it's a Windows Update (or rather a Feature Upgrade problem), a reinstall of VMware might help ... although, usually in this case an application does not work at all, before a reinstall.
