I got error:

Here is my VPN setup (I’m using SSTAP):

Tell me if there any information missed. It must not be error since my VPN has working internet both TCP/UDP.

Have you reviewed WARP with legacy VPN · Cloudflare Zero Trust docs ? If WARP is connected first does it work?

I can’t try connecting WARP client first since I’m bypassing my ISP trick to access free internet if I do that.

I can get free internet with doing this since my ISP didn’t block some cloudflare IP range, so I take advantage that:

my_devices -> ISP (no internet, except some cloudflare IPs) -> vpn_tunneling -> internet

So, I can’t do this:

my_devices -> ISP (no internet, except some cloudflare IPs) -> warp_client (will not connect since warp requires internet access) -> vpn_tunneling (internet)

So, I expect this one:

my_devices -> ISP (no internet, except some cloudflare IPs) -> vpn_tunneling -> internet -> warp -> internet

Don’t worry warp will be connected if I try to using warp normally I mean using another ISP that has internet access.

I notice that API Connectivity is disconnected while connecting warp. But it’s connected if I didn’t try to connect.
