Hi Sergey,

Thank you.

After enabling the "" on the upstream, we are seeing the
following SSL error in upstream:

Thread-7, fatal error: 80: problem unwrapping net record Unsupported record version Unknown-126.133
%% Invalidated:  [Session-20, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384]
Thread-7, SEND TLSv1.2 ALERT:  fatal, description = internal_error

And we are still trying to find the cause of this SSL error.
