I updated fiddler to 5.0.20202.18177 and I constantly get 504 errors when hitting known working end points now. In the previous versions I did not. I also have a number of unit tests that hit these end points and they work every time I run them. So I know the server is working.

Any help or a method to roll back my version of fiddler would be great!

Hi Josh,

Unfortunately, we don't distribute older versions. However, I would like to understand what, if any, changes are impacting the environment and get it working again. Can you share the below items?

1. Output of the Fiddler Log Tab.

2. Session Archive of the 504 Errors.

3. Screenshots of the Fiddler Options dialog.

- This should include, General, HTTPS, Connections, Gateway, Scripting and Extensions.

4. Screenshot of the AutoResponder rules.

Once I have the above information, I can be able to investigate in more detail. Note that any sensitive urls can be redacted for security reasons. We only need the settings and configuration information.

In the meantime, please let me know if you need any additional information. Thank you and I look forward to your reply.

Regards,
