Server not found usually means your browser can’t reach the website’s server. This can happen for several reasons, ranging from local issues on the device or network to problems with the website’s servers or DNS. Key causes and quick checks
- DNS problems: The domain name can’t be translated to an IP address. Try flushing your DNS cache, switching to a different DNS server (for example, Google DNS 8.8.8.8 and 8.8.4.4 or Cloudflare 1.1.1.1), or restarting your router.
- Network connectivity: Sometimes a weak or unstable connection, VPN/proxy interference, or firewall rules block access to certain sites.
- Incorrect URL: A mistyped address or a site that has moved or been removed can trigger this error.
- Server downtime or misconfiguration: The website itself may be offline or experiencing issues.
- Local device issues: Outdated browser, corrupted cookies/cache, or conflicting security software can cause pages not to load.
Common troubleshooting steps
- Check the URL for typos and try loading the site again.
- Refresh and restart the browser or try a different browser.
- Clear your browser’s cache and cookies, then reload.
- Restart your router and computer; if you use a VPN or proxy, disable them temporarily to test.
- Change DNS servers on your device or router and flush DNS cache.
- If possible, test from another network (mobile data hotspot, or a different Wi‑Fi) to see if the issue is network-specific.
- For websites you manage, verify DNS records, server status, and firewall rules on the hosting or CDN provider.
If the issue is specific to a single site you expect to be online, it’s often the site’s fault (maintenance, DNS updates, server outage). If many sites fail to load, focus on your network or device configuration. Would you like step- by-step guidance tailored to your device (Windows/macOS/iOS/Android) and whether you’re seeing this on a particular site?
