Can t connect cloudflare warp vpn in linux

Question

I installed and set up Cloudflare warp in Linux as Cloudflare document.

After "start warp-svc.service" and do warp-cli connect successfully,

I check warp status at https://www.cloudflare.com/cdn-cgi/trace/:

warp=off

And I can't access the blocked websites.

How to solve it? Any help will be appreciated. Thank you!

I think you disabled IPv6 before, I got the same problem with warp-cli after I disabled IPv6. You can re-enble it by:

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0 
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=0 
sudo sysctl -w net.ipv6.conf.<your device>.disable_ipv6=0
