looks like the agent is failing to connect back to the master because of
some SSL cert problem??


curl: (60) Peer certificate cannot be authenticated with known CA
More details here:

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

any ideas how to rectify this?

Hi Aaron,

Could you correlate this message with the server logs and provide them?
If you stop and start the agent you should be able to capture the error if
any on the server side.

To turn on debugging on the agent, edit
also turning on debugging on the server site might help.
