Cannot use Dynamic DNS URL as server address to connect #23

Closed KyamuDog closed 2 years ago

KyamuDog commented 2 years ago

Using No-IP I have created a domain name that will be redirected to my IP to avoid disruptions when it changes as I do not have a static IP with my provider.

Unfortunately using the domain name is not possible at present. It times out every time.

KyamuDog commented 2 years ago

It CAN be pinged, and will resolve to the IP address, but it will never connect

Rythoka commented 2 years ago

Sounds like a port forwarding issue to me. Did you also try connecting directly to the IP address the DynamicDNS resolves to?

KyamuDog commented 2 years ago

Decidedly not a port forwarding issue. The IP address works, and the URL resolves to the correct address when checked. All of the players currently use the IP, but if a power outage occurs (or the IP expires) we get a new IP, which is why I am working on this.

KyamuDog commented 2 years ago

As it's closed source, I can't walk through it's connection process, but perhaps @TastyLollipop can shed some light on that. Is there perhaps some fuckery occurring when parsing an address that has subdomains? example.ddns.net as opposed to something more "normal" like kyamudo.gg It's totally speculation, but it might be related to that, if it has to handle URLS and IP addresses differently (resolving the URL before connecting etc.)

I could see a simple check for multiple '.' in the address field erroneously sending the URL to whatever code handles the direct IP connection or something rather that to the code responsible for resolving to an IP. I do of course make a lot of assumptions here.

I run a server that uses a subdomain with no issues whatsoever. Also, it's not difficult whatsoever to decompile the code if you're so inclined.

KyamuDog commented 2 years ago

Hmm... Not sure then. Like I said, the above was a shot in the dark. Directly setting the A record on a domain I control allows others to connect, but the ddns.net domains do not. Very strange.

All it does it update the A record of that subdomain every so often, so I'm not sure what could be going wrong. On paper they ought to be identical.
