SSL Protocol Error

Hiya, I have just recently created a 5 node HA cluster in Acronis infrastructure and initialised a backup of my servers on VMware using the recommended esxi appliance setup but seem to be getting a SSL protocol error every time I run a backup. I have even tried running a local backup from my local machine to the backup but still I get the SSL protocol error. Has anyone encounter this and how did you remedy it? This is a production node. Any pointers or help would be greatly appreciated. Cheers
