I am trying to install a self-signed certificate using the Zimbra console but I'm getting an error during the process. Information in the CSR has been successfully entered but when I tried to click the install, there was an error message:

Your certificate was not installed due to the error : system failure: exception during auth {RemoteManager: mail.bancnetvan.net->zimbra@mail.bancnetvan.net:22}

I'm using Zimbra Version 8.0.4_GA_5737.FOSS running RHEL 6. I'm doing this in preparation for installing a commercial SSL certificate. Hoping someone could help me.
