It’s a MySQL version issue because MySQL 8.0 and later introduced a new default authentication plugin called **`caching_sha2_password`** , which older clients and connectors don’t recognize. If your server is running a newer MySQL version but your application or client library is built for older versions (like MySQL 5.7 or earlier), the connection will fail since the client can’t handle the new authentication method. This mismatch between the server’s version (and its default settings) and the client’s capabilities is what causes the error, making it essentially a version compatibility problem.

Downgrading MySQL can solve the issue because older versions (like 5.7) use `mysql_native_password`, which older clients and applications support. The problem happens when a newer MySQL (8.x) uses `caching_sha2_password`, but the application’s driver can’t handle it—so it’s both a **server version** and an **application/driver support** issue.
What version of N-Studio are you using ??
