Why does the server send nothing?

The server application likely crashed, timed out, or a firewall dropped the response. The TCP connection worked but no HTTP response was sent.

Can extensions cause this?

Yes, ad blockers or security extensions can interfere. Test in incognito mode (extensions are disabled by default) to check.

Chrome ERR_EMPTY_RESPONSE — Server Sent No Data

Warningchrome

Overview

Fix Chrome ERR_EMPTY_RESPONSE error meaning the server accepted the connection but sent no data back, caused by server crashes, timeouts, or firewall interference.

Key Details

ERR_EMPTY_RESPONSE means Chrome connected to the server but received zero bytes in response
The TCP connection was established successfully (unlike connection refused or timeout)
The server accepted the connection then either closed it or sent nothing
Different from ERR_CONNECTION_RESET where the server actively terminates the connection
Can be intermittent if the server is under heavy load

Common Causes

Server application crashed while processing the request
Server-side firewall or WAF dropping the response after accepting the connection
Proxy or reverse proxy failing to forward the response
Server-side timeout: application took too long and the web server closed the connection
SSL/TLS handshake failure after TCP connection establishment

Steps

1Refresh the page — transient server issues often resolve on retry
2Clear Chrome browsing data: Settings > Privacy > Clear browsing data
3Try incognito mode to rule out extension or cookie interference
4Flush DNS: chrome://net-internals/#dns > Clear host cache
5If the issue is only with one site: the problem is server-side, wait or contact the site owner
