Use tools like `ping` and `traceroute` or `tracert` (Windows) to test network connectivity to the server's IP address. A successful `ping` verifies basic reachability. `traceroute`/`tracert` shows the path the network packets take, which helps pinpoint potential network bottlenecks or firewalls. Use `telnet 3306` (or the MySQL port) from the client to verify whether a TCP connection can be established to the MySQL server's port. If these network tests fail, the problem likely lies outside of the MySQL server itself.
