Discover virtual appliance task failed with an unknown error

I have just installed VMware Replication appliance a few days ago on my virtual environment.

Now every time Update manager starts a scan. The Discover virtual appliance task failed with an unknown error.

Looking at the log4cpp.log file i found this entry

'VADiscovery' 6204 ERROR]  [vaDiscovery, 479] Error during discover VA: Crypto Exception: error:02001002:system library:fopen:No such file or directory:unable to load ssl\vm-10973\cert.pem

does someone knows what this error means ?

I am at a lost on how to resolve this.
