Hello,
My team has started using WARP + Zero Trust a few days ago and we are preparing the release for the whole organization.
However, we are facing a strange situation: when logged in to the Zero Trust team, the app randomly disconnects and only shows Connecting. At that point, local DNS resolution fails and only the public DNS configured in our PC works, avoiding DNS inspection and protection.
The traffic continues going through the WARP network, but all security measures are disabled as the DNS server is not working.
In macOS and Windows, the network connectivity continues working as the OS fallback to the system-defined DNS. In Linux, the DNS fallback is not executed and the computer loses connectivity (no DNS resolution at all).
We have reduced all our configuration to the bare minimum:
- Only check domain name of the user to allow devices
- Only one default device profile with default split tunnel configuration
- No firewall blocking rules
As a bonus, if we manually restart the service of Cloudflare WARP, it successfully connects for the first time but a few minutes after that it enters again in this Connecting state.
This is a problem for us, as we have a highly distributed team and losing connectivity in this random way makes it a stopper for us to release it to the whole company.
Also, we have opened two support tickets, one of them 5 days ago and no response after support checked that we had no other VPN running (we have several domains in the Business plan).
It is hard to believe that there may be thousands of users with this kind of errors happening, so it have to be something related to our configuration.
Any ideas how to fix this?
