The server at example.com cannot be found because the DNS lookup failed. DNS is the network service that translates domain names to IP addresses.
🔍 Try:
Checking the network cables, modem, and router
Reconnecting to your Wi‑Fi or mobile network
Flushing DNS – Run ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (macOS)
Changing your DNS server to a public one like Google (8.8.8.8) or Cloudflare (1.1.1.1)
Disabling any VPN, proxy, or firewall that might interfere with DNS resolution
Checking if the website address is correct — sometimes a typo causes this error
