SSL Connetion (Host Europe) fails, without SSL works - why?

[Philipp Dubrau]

Hello together!

I wan't to connect to a MySQl Database via SSL. Without SSL no problem but with SSL I get an Error. Here are some details:

MYSQL-Datebase Version: 8.0.30-22
Connector Version: odbc-8.0.32-win32 (I need the 32 bit Version for my 32 bit Access Program)
OS: Windows 10 Pro

I dowloaded the SSL key files from my Hoster (hosteurope.de) and have set the database for external access.

Without any SSL-Settings, connection works!

After this I have set up the following SSL Settings:
SSL Key -> Path to key file in PEM Format (ANSI)
SSL Certificate -> Path to Cert file in PEM Format (ANSI)
SSL CA File -> Path to CA file in PEM Format (ANSI)
SSL Key -> Path folder there the 3 files above are stored.
Everythung else is blanc

Then I press Test I get the following Error:
[MySQL][ODBC 8.0(a) Driver]SSL connection error: error:1416F086:SSL routines:tls_process_server_certificate: certificate verify failed[HY000]

What can I do?

Thank you!
Philipp
