Cloudflare Warp (In Windows) is forwarding my public IP as a 172.16.x.x

Cloudflare Warp (In Windows) is forwarding my public IP as a 172.16.x.x on some ISP’s. warp-cli works perfectly for all ISP’s in Linux.

What is it you’re expecting it to do?

We have an Argo Tunnel Setup for Accessing Local resources.
The Argo tunnel also helps us access IP whitelisted domains via the office network

Recently we have been facing issues that these domains started responding with 1020 Access Denied errors and IP being logged in Cloudflare WAF is in the private range 172.16.x.x

This issue appears to be occurring on Windows Cloudflare WARP clients only, and only on some ISPs.
When tested on Linux and Android, this issue does not occur.
The Moment I change to some other ISP it starts to work. So far tested with 5 different ISP’s out of which this issue occurs on 3 of them and not on the other 2.

Finally managed to resolve the issue by myself.

The issue appears due to the Experimental QUIC protocol in Chome. Disabling which resolves the problem
