Hi, I am facing an issue after openssl upgrade to 1.1.1. I have a odbc client with maximum version support up to TLSv1.2 and my database is running with TLSv1.2,TLsv1.3.
The handhake is failing and I am getting following contents on my BIO dump. "15 03 03 00 02 02 56" . If i have understood correctly this is for alert message and But I could not find any reference to alert description at ( https://tools.ietf.org/id/draft-ietf-tls-tls13-25.html#alert-protocol ) corresponding to 56. So, Could you please help me figure out what does this correspond to ? Moreover I have following doubt. -- If my TLSv1.2 client does not handle the "downgrade sentinel " present in server hello ( TLSv1.3 , will it create any problem ? -- In the above example client is receving error such as "SSL Handshake Failure reason [error:1407743E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert inappropriate fallback]." ? Could you please help me to hint me about how to debug this ? Thanks and Regards, Ram Krushna
