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 in https://www.cloudflare.com/cdn-cgi/trace/:

warp=off

And I can't access to the blocked websites.

How to solve it? Thanks

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

  • That was also my problem! thanks. I think warp-cli should be able to pinpoint this and show a message – Luis Antolín Cano Jun 24 '22 at 06:46
  • Thanks, this fixed the issues for me. Post the error messages shown in syslog when IPv6 is disabled to make searching this issue easier. `Aug 8 09:33:35 smsudt systemd-udevd[13876]: CloudflareWARP: Failed to get link config: No such device Aug 8 09:33:35 smsudt libvirtd[1216]: Failed to open file '/sys/class/net/CloudflareWARP/operstate': No such file or directory Aug 8 09:33:35 smsudt libvirtd[1216]: unable to read: /sys/class/net/CloudflareWARP/operstate: No such file or directory` – 2stacks Aug 08 '22 at 14:54
  • safety tricks: Before running those comments first check actually it is disabled or not. Go to `/proc/sys/net/ipv6/conf/all`, `/proc/sys/net/ipv6/conf/default` and `/proc/sys/net/ipv6/conf/` folder. In all folders open file `disable_ipv6` and check the value weather it 0 or something other. This is the value you going to change – mahfuj asif Dec 04 '22 at 05:36

Let check your current status by the command:

warp-cli status

I'm guessing your warp status is: Registration missing :D

For me, I have to run register one more time:

warp-cli register

Now, you can connect successfully with the command:

warp-cli connect

Enjoy the connection!
