Diag not playing nice with Little Snitch

[Tuinslak]

Hey -- seems like running this script generates a different binary name (ie nextdns-diag-16136).

This means every time this runs I need to allow this in Little Snitch's firewall rules. However, the script does not wait and before I can click allow, it already fails in the script.

Do you want to continue? (press enter to accept)
Testing IPv6 connectivity
  available: false
Fetching https://test.nextdns.io
  Fetch error: Get "https://test.nextdns.io": unexpected EOF

For example, I do have IPv6 connectivity:

$ ping6 google.be -c 1
PING6(56=40+8+8 bytes) 2404:e801:200e:227f:8cab:3eee:8919:9502 --> 2404:6800:4003:c03::5e
16 bytes from 2404:6800:4003:c03::5e, icmp_seq=0 hlim=108 time=6.519 ms

--- google.be ping6 statistics ---
1 packets transmitted, 1 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 6.519/6.519/6.519/0.000 ms

And opening tests in the browser works fine:
