TLS 1.3 Support on Windows 10 with MySQL and PostgreSQL

TLS 1.3 Support on Windows 10 with MySQL and PostgreSQL

Issue

When connecting to MySQL or PostgreSQL servers on Windows 10, you may encounter errors if the server is configured to use only TLS 1.3. However, the connection succeeds if TLS 1.2 and TLS 1.3 are both enabled.

Reason

Windows 10 does not support TLS 1.3 at the system library level. This limitation affects all applications relying on the built-in security features of the OS, including MySQL and PostgreSQL clients.

Solution

To resolve this issue on Windows 10, enable TLS 1.2 or TLS 1.1 on the MySQL/PostgreSQL server to ensure compatibility with Windows 10 clients.
Info
Note: Our products utilize the system's security libraries for handling secure connections. As such, support for TLS 1.3 is determined by what the operating system provides.
For more details on TLS protocol support in Windows, refer to the official Microsoft documentation: TLS/SSL Protocols in Windows (Schannel SSP)
