STUBBY: *FAILURE* no valid transports or upstreams available!

[swmiller6]

dig google.com @127.0.0.1 works as expected, however when I edit the reslov.conf to point to 127.0.0.1 and then run dig google.com or dig google.com @127.0.0.0.1 it times out. The error STUBBY: *FAILURE* no valid transports or upstreams available! This is on a raspberry pi3 Here is a copy of my stubby.yml

# Fallback transport options are specified by including multiple values in the
# list.  Strict mode (see below) should use only GETDNS_TRANSPORT_TLS.

Apologies this obviously got missed at the time! I'm closing this now due to the age of the issue but please re-open if required.
