Check Hostname/IP:

Ensure the DB_HOST in your .env file is your public IP (if your database is accessible publicly) or a domain name that resolves to the correct IP.
Allow External Connections:

If your MySQL server is on your local machine, make sure it's configured to accept external connections. You can do this by editing the my.cnf or my.ini file and ensuring that the bind-address is set to 0.0.0.0 or your specific IP.
Additionally, you need to ensure that your router is set to forward the MySQL port (3306) to your local machine.
Firewall Rules:

Check your firewall settings to ensure that the MySQL port (3306) is open for connections from Vercel's IP ranges. You may need to whitelist specific IP ranges.
Use a Remote Database:

If your database is running on your local machine and you experience connectivity issues, consider using a cloud-based MySQL service (like AWS RDS, Google Cloud SQL, etc.) that is designed for remote access.
Increase Connection Timeout:

You might want to increase the connection timeout in your MySQL client configuration. This won’t fix underlying connection issues but could give you more time for the connection to establish.
