Symptoms
HTTPS Inspection is configured to "Bypass" traffic, but eventually the traffic is inspected, while Probe Bypass is disabled (enhanced_ssl_inspection=0)
Running WSTLSD debug (sk105559) during the issue results in the following messages in $FWDIR/log/wstlsd.elg:
The reply is too old
Not expecting other replies for this level (1). Validation failed
OCSP response time obsolete. Response considered unreliable.
.
.
The OCSP reply shows:
isReplyTimeRecent: nextUpdate (0) or thisUpdate (1546409382) not present, assuming information is always available
Cause
Parsing error occurred on the OCSP reply "nextUpdate" field causes a OCSP (CRL) validation failure.
