Warp client on macos CF_HOST_UNREACHABLE_CHECK
Hi im trying to connect to a tunnel from macos using warp client.
Managed to log in but when trying to connect Im facing CF_HOST_UNREACHABLE_CHECK error
I am able to connect successfully using my mobile phone on the same network
logs show a problem with connectivity.cloudflareclient.com

As you can see from the error, something is preventing it from connecting to the connectivity test. Cloudflare's own docs say:
Resolution Check for the presence of third-party HTTP filtering software (AV, DLP, or firewall) that could be intercepting traffic to the WARP IPs. In the third-party software, bypass inspection for all IP traffic going through WARP. To find out what traffic routes through the WARP tunnel, refer to Split Tunnels.Are you behind a firewall or something that could be restricting you, or an AV/etc? Curious that curl works but normal connection doesn't, could be a transient error or something targeted at the WARP Application if you're using AV/a locked down device
not sure the mac is company mac so i assume there is some AV, IT team on a week vacation and wanted to connect back to my home
