Exact reason can be found in tmnxAppPkiCertVerificationFailed notification, handshakeFailure - TLS handshake failed because there was no common cipher, TLS version mismatch or peer rejected our certificate, badPacket - An unexpected or corrupted packet was received, renegotiationFailure - A failure occurred during a renegotiation.
