Port is open, 42420 is open on tcp and udp

ive troubleshot a minecraft server (25565) and that works fine, no issues on there.

But, vintage story keeps saying 42420 is closed, local ipv4 works but only on host machine, LAN does not work on connecting devices to the same router.

Trying to host from ingame by opening to LAN fails to find upnp and says "Internet hosting failed"

turning on advertise says the same thing, server does not show up in server list

I have tailscale and a vpn but the connection is running though my wifi

I've been trying many other various things for the past 2 hours I have no idea what else i could do, I've looked around and nobody seems to be having the same issue.

got some news for you @Taart

you'll need to allow "Vintage story Standalone Server" through your PC's Firewall
i thought it was there by default due to the numerous Vintage Story app that were allowed on mine
but they changed the app name for the server app
for that you go into your settings > Firewall & Network protection > Allow an app through firewall >change settings > allow another app

hope this helps you like it did for me
btw you dont need upnp, its off on my router

This did not work for me, all the same issues I have it all allowed on both the client and dedicated for private and public.
