Request from a Python code only works if Fiddler is open and capturing traffic. If I turn off capturing or close Fiddler Everywhere (for Mac) request response is always 403 (Forbidden). Probably something related to certificates. Can you help me on this?

Hi Claudio,

Can you give more details about your steps - do you use the terminal started from Fiddler Everywhere? Network traffic in this terminal is pointed to Fiddler Everywhere, so once the app is stopped, it is expected that you'll not be able to capture the traffic.

In case you use a normal terminal, we'll need the following details:

1. What is the terminal you are using?

2. What is the Python library you are using for making HTTP requests

3. How do you set proxy on your terminal and Python app - is it through environment variables?

4. What is your Python version?

5. Have you trusted Fiddler's Root Certificate?

 

Looking forward to hearing from you.

Regards,
