Frequently Asked Questions

What does ERR_HTTP_RESPONSE_CODE_FAILURE mean in Microsoft Edge?
This error occurs when the website's server returns a 4xx or 5xx HTTP status code, indicating the server cannot fulfill your request due to client error, server error, or temporary unavailability.
Why does this error only happen on certain websites?
The error is website-specific and occurs when that particular server is down, misconfigured, blocking your IP address, or experiencing high traffic. Other websites work normally because their servers are functioning properly.
Can browser extensions cause ERR_HTTP_RESPONSE_CODE_FAILURE?
Yes, certain extensions like ad blockers, VPNs, or security extensions can interfere with HTTP requests and cause this error. Disabling extensions temporarily can help identify if they're the cause.
Is ERR_HTTP_RESPONSE_CODE_FAILURE the same in other browsers?
While other browsers may display different error messages for HTTP response failures, the underlying cause is the same. Chrome might show 'This site can't be reached' while Firefox shows 'Server not found' for similar issues.
How long should I wait before trying to access the website again?
If the error is due to server issues, wait 15-30 minutes before trying again. For temporary server overload, the website typically becomes accessible within a few minutes to an hour.
