[Solved] pi-hole DNS is no longer reachable after update

I updated to the most recent version of pi-hole, along with a bunch of other things, and I'm finding that pi-hole DNS is no longer accessible on port 53 on the external IP address but works fine on localhost.

My first suspicion was iptables but from a rules perspective it looks fine:

$ sudo iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT

And as far as I can tell pihole is binding to all IP addresses:

$ sudo netstat -lnp | grep 53
tcp        0      0 127.0.0.1:53            0.0.0.0:*               LISTEN      668/pihole-FTL      
tcp6       0      0 ::1:53                  :::*                    LISTEN      668/pihole-FTL      
tcp6       0      0 fe80::2d3e:5cb8:14cd:53 :::*                    LISTEN      668/pihole-FTL      
udp        0      0 127.0.0.1:53            0.0.0.0:*                           668/pihole-FTL      
udp6       0      0 fe80::2d3e:5cb8:14cd:53 :::*                                668/pihole-FTL      
udp6       0      0 ::1:53                  :::*                                668/pihole-FTL      
unix  2      [ ACC ]     STREAM     LISTENING     16253    705/systemd          /run/user/1000/systemd/private
unix  2      [ ACC ]     STREAM     LISTENING     14538    769/postgres         /run/postgresql/.s.PGSQL.5432

What else can I check to help get this resolved, network stuff is not my strong suit so some guidance would be greatly appreciated.

[Solved] there was a new configuration file saved as pacnew, replacing my current config with that one resolved the issue.
