IPv6 DNS Issue #1

Open JacobJoachim opened 2 years ago

JacobJoachim commented 2 years ago

Symptom: MQTT connection in node-red appear disconnected. Cause: No DNS available. Note: Only IPv6 public address configured (modem). DNS lookups only work for IPv6 hosts (using tailscale DNS service).

Unknown if modem initially received IPv4 address on previous boot.

Reboot resolves issue.
