Since upgrading one of our ESXi Host servers from v4.1 to v6.0, the server shows as "(Disconnected)" in the VM Explorer "My DataCentre" view and backup tasks are failing. (We are using the free edition of ESXi without vCenter).
When I re-run the VM Explorer "Edit Server" wizard, the "Test Connection" stage fails with the following error:
"ESX Connect Error: The request was aborted: Could not create SSL/TLS secure channel."
Please find attached a screenshot.
However, the vSphere Client v6.0 successfully connects to the ESXi Host.
SSH is enabled and I have tried re-starting the Management Agents in the ESXi Direct Console User Interface (DCUI). I have also tried enabling the ESXi Shell without success.
My next thought is to re-generate the SSL certificate on the ESXi host but can't see why that would have any effect if the vSphere Client is working ok.
I would be grateful for any help re the meaning of the error messages above and possible solutions.
Thanks.
