Removed all policies and started again with default setup.

Cloudflare Engineer was able to reproduce the issue on his machine connecting to my tenant (sorry not sure if that is the right terminology).

Register WARP with Zero Trust
Authenticate
Client is now registered
Click Connect and after about 10 seconds, get the CF_DNS_LOOKUP_FAILURE error.
Lots of 10031 errors in daemon.log

Hi all.
Turns out I had created a Default DNS Location without DNS over HTTPS (DoH) enabled. Once I created a new Default DNS with that turned on, WARP was able to connect.
