ERR_EMPTY RESPONSE- Unable to navigate inside the web app when Fiddler capture is enabled

[Deepti]

I am trying to capture API endpoints by enabling fiddler capture, however, my application do not proceed, instead, it throws an error as ERR_EMPTY_RESPONSE.

 

If I disconnect the Fiddler application works fine, but then I am unable to capture the request/response

Hello Deepti,

 

The status code usually indicates that you probably don't have an internet connection, suggesting that your application is not going through the Fiddler proxy and effectively lacks internet access when the Fiddler proxy is on. Verify that the application you are testing uses the system proxy and respects the Fiddler proxy change.

Can you let me know, how can I - Verify that the application under test uses the system proxy and respects the Fiddler proxy change.

That depends on the application itself. There are specific proxy options and configuration files depending on the development tool/framework/library.
