[titoluna07]

I am having a problem while testing Proofpoint connectivity with splunk, I am getting this ssl=falseon the metrics.log
is that normal?
anyone can help me?

I don't know how to see any other errors, everything seems ok,
On Proofpoint portal, about the connectivity test using port 6514 page says:
OK: tcp
FAIL: tls

Thanks!
