Fiddler not working with iOS 10.3.2 version

I've been using Fiddler to debug iOS app and recently I just updated my iOS device to the latest iOS 10.3.2 version. Since then I cannot see any data in Fiddler and I've tried to reinstall FiddlerRoot certificate, but I'm unable to open "Fiddler Echo Service" webpage, so I'm unable to install FiddlerRoot certificate. Does anyone else have the same issue?

    According to Wireshark capture it seems the [SYN, ACK] packet is ignored by iOS device, it seems that there's a bug in this iOS version, because after updating to iOS 10.3.3 everything works fine.

    >I'm unable to open "Fiddler Echo Service" webpage 

    This means that there's a problem in the connectivity between your device and the PC running Fiddler. Have you disabled the cellular connection on the device? Was the firewall on the PC activated? Can you reach the echo service from a different device?
