intermitent certicate chain error on outbound HTTPS

getting an intermittent error on all outbound HTTPS connections, Server certificate rejected by ChainVerifier.

if I run the attempted outbound login (to multiple customers) if will work fail sometime and be fine at other times.

Anyone seen this type of behavior before in IS 9.7?
this is while running the pub.client:soapClient service.

Problem turned out to have nothing to do with the IS.

Our outbound traffic was getting routed through two different paths, one of which is meant for web browser traffic only and required a cert that was not in our truststore.

Rather than load a new cert our network team bypassed our traffic form the web browser only route.

Glad to hear, you resolved your bug. Thanks for updating the thread.
