【MySQL】Communications link failure, The last packet sent successfully to the server was 0 milliseconds

When I opened DataGrip today, it suddenly gave me such an exception. 🤬

Solution:

  1. Check if the MySQL server is already running. On Windows, you can check if the MySQL service is running through the "Services" application. If it is not running, start it.
  2. Check if your network connection is working properly. If your network connection is not working properly, you may not be able to connect to the MySQL server.
  3. Check if your MySQL server configuration is correct.

Done
