Hello all,

I have seen various threads about this topic but although I followed all the recommendations, nothing had a successful result. I have installed fiddler on my new Win10 laptop. Hotspot is created through NoWifi windows app since the driver does not directly support hotspot. Mobile is connecting normally to the hotspot and has access to internet without a problem (sharing my ethernet with the mobile hotspot). When I modify the wifi connection on the mobile to give the ip and port for the fiddler proxy, the mobile has no access to the internet any more.

Fiddler has:

  • Enabled Capture HTTPS CONNECTs
  • Enabled Decrypt HTTPs traffic
  • Enabled Allow remote computers to connect

And has been restarted after the settings have configured.

When I connect to the wifi with the mobile, I try to reach the ipv4.fiddler:8888/ page but I get Site can't be reached...

I have also tried to change the certificate generator to BouncyCastle but this did not work either.

Any ideas would be greatly appreciated.

Thank you very much,

Haris

Hey Haris,

Did you follow all the steps listed in our documentation:

- Android: https://docs.telerik.com/fiddler/configure-fiddler/tasks/configureforandroid 

- iOS: https://docs.telerik.com/fiddler/configure-fiddler/tasks/configureforios 

 

Also, keep in mind the mobile device and your laptop needs to be in the same network, which does not mean you should create a hotspot from your laptop - it is enough to connect to the same router and it should work.

You'll have to use BouncyCastle to have the whole setup working properly.

Hope this helps.

Regards,
Rosen Vladimirov

Thank you very much for the hints. It turns out it was after all the firewall. Despite the fact that the IT team had changed the policy for me, it seems that the policy was not applied properly. After searching the logs, I saw that the firewall was blocking the incoming traffic on the fiddler IP and port. It took them about 1 week of searching and retrying various things to get it done and finally today it was fixed.

I use the configuration I used to work with, hotspot on laptop, shared network and connect to it with manual proxy settings.
