cf_dns_lookup_failure
I am using latest version of the warp client on Windows 11. when enabling warp I goes to connecting and than fails with dns lookup error
from log and network interfaces I see that the client is able to successfully change the dns servers to 127.0.2.2/3 however the dns resolution does not work
there is nothing bound on port 53 at my pc
any idea on investigating this further ?
I could not spot anything useful from warp-debug

Hi. You could try these steps:
1. Verify that the network the user is on has DNS connectivity.
2. Verify that DNS resolution works when WARP is disabled.
3. Ensure that no third-party tools are interfering with WARP for control of DNS.
4. Ensure that no third-party tools are performing TLS decryption on traffic to the WARP IP addresses.

hi I did check the link but no luck. there is no 3rd party tool installed afaik that is interfering with warp. warp can Bind to Port 53 but the name resolution is failing. dns works fine without warp
I haven't configured any gateway dns policies in the zero trust portal . though I assume this shouldn't be a problem?
