The VMware support contacted me this week regarding my error with the following email:
----------------------------------------------------------------------------
In reviewing the logs, we can see the below error, quite a few time:
Caught Exception : Exception : org.apache.axis.AxisFault Message : ; nested exception is:
- javax.net.ssl.SSLHandshakeException: Unsupported curve: 1.2.840.10045.3.1.7 StackTrace :
The below KB deals with this issue:
Communication fails in vSphere Data Protection with vCenter Server 5.5 Update 3 (2146825)
http://kb.vmware.com/kb/2146825
This KB works for other versions, not just VDP 6.1
------------------------------------------------------------------------------------------
I was not able to apply the hotfix successfully. There was always an error during the installation.
Yesterday I connected via webex to the VMware support. After two hours of troubleshooting we decided to deploy a new VDP. VMware recommends to install VDP appliance version 6.1.3 which is compatible with my vCenter server 5.5. Now it works!
