MySQLClient error resolving

When using the example code provided for the MySQLClient library (MySQLClientExample - | Mbed), I have an error during the connection to the MySQL server heberged on my Windows 11. The error code is 2, and while I find some results about it, none of them help me for my situations.

Does anyone had this problem when using this library and solved it ? If so, could you please tell me how ?


the code what you use is running under obsolete Mbed version and is 12 years old.
The error 2 is probably an protocol errror (Line 50).
