Fixing the SSL Unsupported Protocol Error on Raspberry Pi While Connecting to MySQL

If you're using a Raspberry Pi and have encountered the frustrating SSL: UNSUPPORTED_PROTOCOL error while trying to connect to a MySQL database, you're not alone. This issue can be baffling, especially when the same operation works perfectly on other platforms. In this guide, we’ll explore how to troubleshoot and solve this problem so you can get your database connection up and running smoothly.

Understanding the Problem

When you try to establish a connection to MySQL from your Raspberry Pi using SSL, you may receive an error message like the following:

This indicates that the current SSL/TLS version being used for the connection attempt is not supported. In many cases, this happens because the minimum SSL/TLS version set in your OpenSSL configuration file is higher than what the MySQL server supports.

The Solution

Fortunately, resolving this issue is relatively simple and can be achieved by modifying the OpenSSL configuration file on your Raspberry Pi. Here is a step-by-step guide you can follow:

1. Accessing the OpenSSL Configuration File

To change the minimum SSL/TLS version, you'll need to edit the OpenSSL configuration file. You can do this by running the following command in your terminal:

2. Locate the MIN_VERSION Setting

Once you have the configuration file open, scroll down to the end of the file. You might find a line that specifies the MIN_VERSION for SSL/TLS protocols.

3. Changing the Version

You will want to change the MIN_VERSION from 1.2 to 1.0. The line should now look something like this:

Changing this setting allows your connection to fall back to using older, and more widely compatible, versions of the SSL/TLS protocol.

4. Save the Changes

Once you've made the necessary changes, save the file by pressing CTRL + X, then Y to confirm, and ENTER to exit.

5. Restart the MySQL Service (Optional)

Although not always necessary, restarting the MySQL service can help in applying the changes smoothly. You can do this by running:

6. Test the Connection Again

Finally, attempt to connect to your MySQL database again. If all goes well, you should be able to make a successful connection without encountering the SSL unsupported protocol error.

Conclusion

By following the steps outlined above, you should be able to fix the SSL unsupported protocol error on your Raspberry Pi. Adjusting the minimum version of SSL/TLS in the OpenSSL configuration is a straightforward solution that can pave the way for a successful connection to your MySQL database. If you continue to face issues, consider checking other components of your network setup or the MySQL server settings.
