MySQL Connector 6.9.9 and TLS 1.2

I have a web app (.net 4.7) that connects to mysql database using mysql connector 6.9.9

My web app is TLS 1.2.
Windows server 2016 - TLS 1.1 and 1.2 enabled
MySQL DB: 5.7.22 supports TLS 1.1, 1.2 but ssl_version = tls 1.1 because there are other applications that currently is on 1.1

Question:

If we disable 1.1 on windows server my app fails with

"The client and server cannot communicate, because they do not possess a common algorithm"

If we enable 1.1 it works fine but the connection from my web app to db server uses TLS 1.1

Why would my web app make a connection with TLS 1.2 when the protocol is set to TLS 1.2 in the app.

Please could someone help in this regards I have been sitting on this for days.
