If Navicat cannot log in to TDSQL MySQL version, here are some steps you can take to troubleshoot the issue:

  1. Check Connection Parameters: Ensure that the host, port, username, and password are correct. For example, if your TDSQL MySQL instance is hosted on a specific IP address and port number, make sure these details are accurately entered in Navicat.

  2. Network Connectivity: Verify that there are no network issues preventing Navicat from connecting to the TDSQL MySQL server. You can try pinging the server IP address from your local machine to check basic connectivity.

  3. Firewall Settings: Ensure that the firewall settings on both your local machine and the TDSQL MySQL server allow for the necessary traffic. The default MySQL port is 3306, but this can be different if you have configured it otherwise.

  4. Database User Permissions: Confirm that the MySQL user has the necessary permissions to connect from your IP address. You can check and modify user permissions using SQL commands like GRANT and REVOKE.

  5. TDSQL Specific Configuration: TDSQL might have specific security or network configurations that need to be considered. Refer to the TDSQL documentation for any additional steps required for Navicat connectivity.

  6. Use Tencent Cloud Console: If you are using TDSQL hosted on Tencent Cloud, you can use the Tencent Cloud Console to manage your database instances and check for any configuration issues.

For example, if you are trying to connect to a TDSQL MySQL instance hosted on Tencent Cloud, you can use the Tencent Cloud Console to verify the instance's network settings and ensure that your local IP is allowed to connect.

If you continue to experience issues, consider reaching out to Tencent Cloud support for further assistance. They can provide more detailed guidance tailored to your specific setup.

Additionally, you might find the following Tencent Cloud services helpful for managing and connecting to your TDSQL MySQL instance:

  • Tencent Cloud Database Management Center: Provides a centralized management interface for your databases.
  • Tencent Cloud Network Security: Offers tools to manage firewall rules and security groups to ensure proper connectivity.

By following these steps and utilizing the available tools, you should be able to resolve the login issue with Navicat and TDSQL MySQL.
