Ensure your MySQL configuration (`my.cnf` or `my.ini`) is set up correctly. Key settings to check include:
51+
52+

53+
- `wait_timeout`
54+
- `interactive_timeout`

### Step 3: Monitor Logs
57+
58+
Check MySQL logs for any additional error messages that might give more context to the issue. Logs are typically located in `/usr/local/var/mysql`.
59+
60+
### Step 4: Verify Network Stability
61+
62+
Ensure your network connection is stable, as intermittent connectivity can cause these types of errors.
63+
64+
## Additional Tips
65+
66+
- **Regular Maintenance**: Regularly check and maintain your MySQL server to prevent such issues.
67+
- **Backup Data**: Always backup your data before making any significant changes.
68+
69+
By following these steps, you should be able to resolve the "MySQL server has gone away" error and continue your development smoothly.
