Severity: 3-Major


BIG-IP system rejects SSL forward proxy connections due to expired CA certificates present in ca-bundle even though other, valid CA certificates exist.


SSL handshakes will fail.


-- Forward proxy is enabled in client and server SSL profiles. -- A valid CA certificate is followed by an expired CA certificate in ca-bundle.


Remove all invalid trusted (i.e., expired) certificates from the certificate chain and replace them with a valid trusted certificate.

Fix Information

Fixed the certificate verification issue that was leading to SSL handshake failure.
