I've set up a DNS record (on Cloudflare) pointing to the IPs of one of the servers on my network, which I'm trying to connect to with my MacBook that is set up as an external client, but whenever I try to connect to it, I get Connection Refused. My web server doesn't log the connection attempt, so I don't think it's getting that far, and I have tried disabling my firewall, which hasn't worked, so I don't think it's that either (but I'm not 100% on that). Could it be a configuration issue with Netmaker?
