This is usually caused by a DNS resolution issue.

Ensure you can resolve the hostname of the ESX server and Virtual Machine Host name.

You may need to Remote the VM from Inventory, and Re-Add to Inventory.

Yes. Only remove from inventory, not delete from disks.

I think you will need to explain, how you are logging in from the Internet onto you LAN?

Is there a firewall present, and Are all the ports open for communcation?

Check the ports that need to be open here

443, 80, 902 and 903 TCP
