[Freeswitch-users] Weird: Cloudflare 1.1.1.1 DNS server not working with sofia_dig

[Podrigal, Aron]

Hi,

I am experiencing weird behavior.

I have my nameserver set to 1.1.1.1, doing sofia_dig returns no results,
one request out of five succeeds.

- When I do a dig / host lookup directly outside freeswitch using 1.1.1.1,
it works.
- sofia_dig with any other DNS server (8.8.8.8, 9.9.9.9 etc) works.

PCAP shows DNS traffic being sent and received normally. In the non working
scenario, the response from 1.1.1.1 simply has zero  ips.

See below.
