Is there a way to verify that it works?

Hi, I’ve been using the cloudflare warp on android and often connected through a mobile hotspot. One thing I noticed lately is that I’m unable to access the internet nor there’s any traffic going on with warp enabled. But after disabling it, I’m able to continue access the internet.

This is a concerning issues that it is high likely that the ISP is taking preventive measure against user going for warp vpn and I wanted to know if there’s a way that to verify the dns server and the warp vpn would work on ISP before I really going to subscribe to an internet line?

You can just visit with your browser. It will tell you if you are using as DNS.

You can also go to, which will tell you which resolvers your computer/phone is using.
