Unable to connect to the requested VDP appliance

Today I came across a situation where I am unable to connect to my VDP appliance and come up with below error.




there is no problem connecting to VDP configuration.

  • In the /usr/local/avamar/var/vdr/server_logs/vdr-server.log file, you see an entry similar to:

    YYYY-MM-DD HH:MM:SS,MS ERROR [$1]-server.VDRServer: VDRServer.getVCenterClient cannot obtain VCenterClient  java.lang.NullPointerException: VCenterClient list is empty

  • Also in the vdr-server.log file, you may see an entry similar to:

    YYYY-MM-DD HH:MM:SS,MS INFO [http-xxxx-exec-x] -impl.X509TrustChainKeySelector: Failed to find trusted path to signing certificate. 


This issue occurs with the date and time doesn’t match with VDP appliance and vCenter server or ESXi host.

Check the ntp settings are configured correctly on your VC and ESXi hosts. To resolve the issue stop the MCS service on the VDP appliance and start it again .
#dpnctl stop mcs

Once stopped start it again

#dpnctl start mcs

Please follow the KB Could not connect to the requested VDP appliance
