Added a note where these instructions may be incomplete on how to setup workaround. Also noted that issue was prominent on AT&T accessing Cloudflare.

**NOTE** The changes to `/etc/pihole/setupVars.conf` and `/etc/dnsmasq.d/01-pihole.conf` may potentially block off DNSCrypt from reaching an external authoritative DNS server.
A workaround is to set one server in `setupVars.conf` and `01-pihole.conf` to use the IP address of an authoritative server on the net.
This was noted in one case on an AT&T U-verse connection when attempting to use Cloudflare's DNSCrypt service at 1.1.1.1.
For example (fixing Cloudflare's 4/1 service):
`PIHOLE_DNS1=1.0.0.1`
`server=1.0.0.1`
This allows Pi-Hole to bypass "AT&T's block on the 1.1.1.1 IP"https://blog.cloudflare.com/fixing-reachability-to-1-1-1-1-globally/ address and use Cloudflare's 4/1 service to properly authenticate requests.
