- Stopping the MySQL server.
- Starting MySQL in safe mode with the
--skip-grant-tablesoption. - Using the MySQL command line to update the password.
2. MySQL Server Not Running
Ensure that the MySQL Server is indeed running. If it’s stopped, start it again and try connecting through Workbench.
3. Firewall Issues
Sometimes, firewalls block the MySQL port. Make sure that port 3306 is allowed through your firewall. Check your firewall settings and make necessary adjustments.
