Egypt DPI no internet issue
When connected using Xray with socket tun in iOS in that case facing no internet connection issue for Egypt country
Try to use Wireshark to track the network traffic. I think it is NOT the problem of libXray.
Your setup is wrong im sure about that cause there's no reason that it will not work. Im using it on production apps and they are running smoothly

So according to last shared code it's working but half of the internet we can say where application using socket or any other communication which not via http in that case no internet. Please review and let me know where I have made wrong things.
In advance Thanks

Using above code having issue for no internet.
Using below code internet working fine but whats and other some application not working PacketTunnelProvider.swift (Only Internet working some apps not )

So according to last shared code it's working but half of the internet we can say where application using socket or any other communication which not via http in that case no internet. Please review and let me know where I have made wrong things.
In advance Thanks
DNS
I’ve tried updating and removing the DNS, but the issue remains the same. The problem occurs specifically when someone located in Egypt uses the VPN—they still experience the issue.
