From the steps listed as solution 1, it looks like that you have missed the installation and enablement of the Fiddler Root certificate on the Android device. This certificate is needed so that Fiddler could capture secure traffic. Note that you will be able to capture traffic only from browsers (that are using the system proxy) but not from 3rd-party Android applications (where you need access to the code base so that you could explicitly allow the Fiddler proxy as discussed in the very same documentation article)
i had read this doc:
And do like this,but it's dosn't work.
system: windows 10
1.https- capture https traffic(checked)
2.https - ignore server certficate errors(checked or unchecked)
4.connections-act as system proxy as startup(checked or unchecked)
5.connections-allow remote computers to connect
6.gateway - use system proxy or no proxy
1. pc and mobile use same wifi,like mywifi
2.use ifconfig check the ip address, ipv4 :192.168.2.154, mask:255.255.255.0, gateway：192.168.2.1
3. set mobile wifi proxy, host: 192.168.2.154, port: 8866
1.use the windows hotspot, mobile connect to the pc hotspot
2.use ifconfig check the ip address, ipv4 :192.168.137.1, mask:255.255.255.0, gateway：none
3. set mobile wifi proxy, host: 192.168.137.1, port: 8866
open or close live traffic
open link 192.168.2.154:8866(192.168.137.1:8866) in pc browser, it's work.
open link 192.168.2.154:8866 in mobile browser, it's doesn't work(iphone and android).
