Unable to capture traffic on macOS

started a topic about 2 years ago

I posted before but unable to find the topic again. Not sure what happened. So I am posting again.

I am using macOS Catalina 10.15.7.

I am able to start Fiddler Everywhere and login.

But it's not able to capture traffic.

After searching the site, I found the proxy are not checked when fiddler is opened.

https://docs.telerik.com/fiddler-everywhere/knowledge-base/troubleshoot-mac-proxy-settings

Following this: https://docs.telerik.com/fiddler-everywhere/knowledge-base/troubleshoot-traffic-capturing

curl command works but not able to capture traffic from chrome or firefox.

Please help!

Hello Ada,

Thank you for reaching out to us!

If possible please follow the steps described in this thread. The steps will provide us with additional information about the issue you are facing and this way we could investigate further. For your convenience, I am also posting the steps with the link to the custom build here:

1.Open this URL (NOTE: it is a new build) and download the .dmg file. Please note that in some cases SharePoint does not show the actual file the first time when the URL is opened. If that happens on your side, please try opening it again and you should see the file.

2. Install the downloaded .dmg file. This is a special version prepared for this case - 1.1.0-ticket11326. You'll probably be asked to replace the existing application, you can select to do it.

3. Delete the ~/.fiddler directory.

4. Delete ~/Library/Application\ Support/Fiddler\ Everywhere directory

5. In Finder open the Applications directory.

6. Find the just installed version of Fiddler Everywhere and double-click it.

7. In the opened screen you should be asked to sign up, but there will be a button to sign in. Please use it and try to sign in with your credentials.

8. Wait a couple of minutes, for example 2-3. If the application is still in the loading screen, please close it. If the application loads, please try to disable/enable capturing and see if it changes something.

9. Get the logs from ~/Library/Application\ Support/Fiddler\ Everywhere/Logs directory and send them to us for investigation. NOTE: There will be at least three files there, we'll need all of them.

10. Stop the application.

11. Delete the ~/.fiddler directory.

12. Delete ~/Library/Application\ Support/Fiddler\ Everywhere directory

13. Try to run it from a terminal, i.e. execute:

$ open /Applications/Fiddler\ Everywhere.app/

14. In the opened screen you should be asked to sign up, but there will be a button to sign in. Please use it and try to sign in with your credentials.

15. Wait a couple of minutes, for example 2-3. If the application is still in the loading screen, please close it. If the application loads, please try to disable/enable capturing and see if it changes something.

16. Get the logs from ~/Library/Application\ Support/Fiddler\ Everywhere/Logs directory and send them to us for investigation. NOTE: There will be at least three files there, we'll need all of them.

17. Download the latest official version of the application from here.

18. Install the latest official version. This way you'll not be stuck with this custom version (as mentioned earlier this is a custom version without auto-update functionality in it).

Thank you all in advance for your cooperation!
