I use Fiddler Classic.

I enable Decrypt HTTPS and Trust Certificate.

Most websites can capture traffic, but some website display error: Err_Connection_Reset. How to fix it?

Thanks for reading!

Hi Nam Le,

 

Try resetting the FIddler certificates through Tools > Options >  HTTPS > Actions > Reset All Certificates. After that, if your application is no using the OS certificate store (like Firefox) reinstall the Fiddler certificate in the application as well.

The provided URL is working on my side - it is redirecting to https://giaitri.shopee.vn/shopee-delivery/web.html which is to be expected (as I probably need authentication to use the specific CID path)

Still unable to reproduce the issue, which suggests that there might be a local configuration issue related to the security certificates. Try disabling any antivirus and security tools that are running alongside Fiddler and re-issue your request. Alternatively, try the above with the new Fiddler Everywhere and let us know if you are experiencing the same issue.
