Fix UnresolvedAddressException

✅ Solution

UnresolvedAddressException in Selenium usually means the WebDriver is trying to connect to a hostname or IP address that it cannot resolve. Ensure the Selenium Grid hub/node addresses are correctly configured and accessible from the machine running the tests, and verify there are no typos or network connectivity issues preventing resolution. If using hostnames, confirm they are resolvable via DNS or present in your machine's hosts file.
