Test on another network. If only you're affected: disable VPN/proxy and extensions, clear cache, flush DNS and reset Winsock. If everyone is affected, the website's server is crashing or timing out. Site owners should check error logs and timeouts.

What ERR_EMPTY_RESPONSE means

ERR_EMPTY_RESPONSE (“example.com didn’t send any data”) means the request was accepted and then dropped silently. Servers do this when a script crashes, a PHP/worker process hits a timeout or memory limit, or a firewall rule drops the request.

Symptoms

  • “This page isn't working. Example.com didn’t send any data. ERR_EMPTY_RESPONSE”.

Why ERR_EMPTY_RESPONSE happens

  • Network filters, VPNs or extensions.
  • Corrupted network settings.
  • Server crashes, timeouts or firewall rules.

Try these fixes

  1. Check another network/deviceMobile data is the quickest test.
  2. Disable VPN, proxy, extensionsThen reload.
  3. Clear cache and reset networkClear cached files; run ipconfig /flushdns and netsh winsock reset, then restart.
  4. Site ownersCheck web server and PHP/app error logs at the failure time; raise timeouts or memory limits; review WAF/firewall rules.

Command

ipconfig /flushdns
netsh winsock reset

Elevated Command Prompt; restart afterwards.

How to tell it worked: The page returns content instead of the error.

Avoiding it in future

Keep network software minimal; site owners should monitor server errors.
