### Step 3: Monitor Logs

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`.

+
### Step 4: Verify Network Stability

+
62
+
Ensure your network connection is stable, as intermittent connectivity can cause these types of errors.
