Thanks, but no cigar.

The problem is not with SSL libraries.
The problem is with the new Client authentication method introduced with MySQL 8.0.

The JTAlertV2 MySQL support uses a library that wraps the libmysql.dll client file.
Both the library and the dll are old and do not support the new authentication method of MySQL 8.0.
At this time, I have been unable to locate a new library (I don't expect I will).

I was able to workaround this by enabling Legacy Authentication on the server.


I understand this may not be an option for some MySQL Server users, but it is the only fix at this time.

BTW, this change broke many MySQL client applications when first released, including at one time, the official MySQL workbench app.

FWIW, JTAlertV3 will not have this problem as it uses the official Oracle .NET MySQL connector.
