Opened: Dec 30, 2021

Severity: 3-Major

Symptoms

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

Impact

SSL handshakes will fail.

Conditions

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

Workaround

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.
