How to Fix MySQL Error 2026 - (CR_SSL_CONNECTION_ERROR) SSL connection error

MySQL is a popular open-source relational database management system used by many websites and applications. It provides a secure and efficient way to store and retrieve data. However, sometimes users may encounter errors while connecting to the MySQL server. One such error is the MySQL Error 2026 - (CR_SSL_CONNECTION_ERROR) SSL connection error. In this article, we will explore the causes of this error and provide solutions to fix it.

Causes of MySQL Error 2026

The MySQL Error 2026 occurs when there is an issue with the SSL connection between the client and the server. SSL (Secure Sockets Layer) is a cryptographic protocol that provides secure communication over a network. The error can be caused by various factors, including:

  • Incorrect SSL configuration
  • Expired or invalid SSL certificates
  • Firewall or network issues
  • Incorrect MySQL server settings

Fixing MySQL Error 2026

Here are some steps you can take to fix the MySQL Error 2026:

1. Verify SSL Configuration

Check the SSL configuration on both the client and server sides. Ensure that the SSL settings match and are correctly configured. Verify the SSL certificate paths, key files, and other SSL-related parameters.

2. Renew or Replace SSL Certificates

If the SSL certificates have expired or are invalid, you need to renew or replace them. Generate new SSL certificates or obtain valid ones from a trusted certificate authority. Update the SSL certificate files on both the client and server sides.

3. Check Firewall and Network Settings

Firewalls or network settings can sometimes block SSL connections. Ensure that the necessary ports (usually 3306 for MySQL) are open and not blocked by firewalls or other security measures. Check network configurations and make sure there are no restrictions on SSL connections.

4. Verify MySQL Server Settings

Check the MySQL server settings related to SSL connections. Ensure that the "ssl-ca," "ssl-cert," and "ssl-key" parameters are correctly set in the MySQL configuration file. Verify that the MySQL server is configured to use SSL connections.

5. Update MySQL Client Libraries

If you are using a MySQL client library, ensure that it is up to date. Outdated client libraries may have compatibility issues with SSL connections. Update the client libraries to the latest version to resolve any potential problems.

6. Restart MySQL Server

After making any changes to the SSL configuration or MySQL settings, restart the MySQL server to apply the changes. This ensures that the server uses the updated SSL settings and resolves any temporary issues.

Summary

MySQL Error 2026 - (CR_SSL_CONNECTION_ERROR) SSL connection error can be caused by various factors, including incorrect SSL configuration, expired or invalid SSL certificates, firewall or network issues, and incorrect MySQL server settings. To fix this error, verify the SSL configuration, renew or replace SSL certificates, check firewall and network settings, verify MySQL server settings, update MySQL client libraries, and restart the MySQL server. If you are experiencing this error, contact your system administrator or refer to the MySQL documentation for further assistance.
