When using the TUNNEL_DNS_ADDRESS parameter other than "0.0.0.0" the Healthcheck will report Unhealthy
For example: TUNNEL_DNS_ADDRESS=192.168.1.38
The Healthcheck command used is "dig +short @127.0.0.1 -p $TUNNEL_DNS_PORT cloudflare.com A || exit 1"
Changing it to "dig +short @$TUNNEL_DNS_ADDRESS -p $TUNNEL_DNS_PORT cloudflare.com A || exit 1" will solve this.
