I have been through as many relevant Learning Centre tutorials and U-tubes as I can find but I still have a basic problem with running the Postman Proxy.
My system runs on the local network - consisting of a RaspberryPi Pico-W as server and an 8" Samsung tablet as client. (project courtesy of the Bytes-n-Bits site). The Pico is battery powered and contains all the necessary software. It has three coloured LEDs and analogue inputs from a potentiometer and the CPU temperature.
Without Postman, the tablet will access the browser page with four buttons and two gauges . It correctly switches the LEDs on and off and the gauges respond to the pot and the CPU temperature.
When I set up Postman, I enable the proxy as your tutorials and Youtubes, I set up the proxy and destination IP addresses in the tablet (and save) and in the browser it shows the page correctly, operates the LEDs and the gauges respond. But, there is no captured traffic!
I wonder if the problem is authentication, but I can’t find any relevant guidance and I’ve tried changing the auth to various settings with no effect. The system is entirely HTML and bespoke, apart from the fancy graphics for the gauges. So I can’t think it could be protected. My only reservation is that the video ‘Capturing API calls with a Proxy’ (3:07) calls for installing a security certificate for HTTPS traffic. I don’t recall doing this. Could this be the stumbling block? Or perhaps I have missed something I should have done.
Oh, one more thing. Because I had tremendous difficulty installing the normal Postman I finished up installing Postman Canary-11.2.14 Could this be a factor?
