Posted: 2 years agoAryaa PEGA replied to Srikant.NDid you check if the certs are still valid or expired?

This should show us why the SSL handshake is failing, is it because of the certificates or wrong configuration. Posted: 2 years agoguzil PEGA replied to Srikant.NHi, Could you provide the output from the below command: openssl s_client -state -status -connect <host:port> | openssl x509 -text -connect host:port - who to connect to (default is localhost:4433) Thanks, Lukasz Accepted Solution Posted: 2 years agoJoelMcLeish PEGA replied to Srikant.NThis error can occur when the service does not support the version of TLS you are attempting to connect on; if you are on TLSv1.0 please change to TLSv1.2, this is a negotiate down protocol. I'm also suspect of the timing, there was an industry wide uplift to TLSv1.1+ at the start of July for any applications that require PCI-DSS compliance, this may be why this has changed.
