Problem – Veeam ONE Monitor could not connect to…
You try and connect to a supported vCenter server version with Veeam one but it pops up with the following error
Veeam ONE Monitor could not connect to xxx . ESX version is no longer supported. Refer to system requirements for more information
Log onto the vCenter server with the vSphere client and make sure all the ESXi hosts being managed are of a supported version. A less than ideal work around is to add all the ESXi servers individually to Veeam ONE.
