Description:
Hello!

I use libmariadb version 3.1.15 from vcpkg on Windows machine.

When I run mysql_real_query_start() after creating connection with ssl mode it fails with error code 2013 and error msg "Lost connection to MySQL server during query".

If I run the same code on Centos7 it works fine.

The problem is in mysql_real_query_start(). It sends not encrypted request to server and therefore server closes the connection. As the result we get error msg "Lost connection to MySQL server during query".

How to repeat:
1) Download libmariadb version 3.1.15 and build on Windonws 10 Pro;
2) Download mysql server version 5.7.39, install on the same machine where libmariadb was built and run;
3) Create c++ test project with code from the private comment;
4) Build project and execute the program;
