Modded MPT Results in infinite waiting for players

[wooden tapir]

me and my buddy were trying to set this up last night, we got it to work fine on vanilla factory. but after loading SAIN, BigBrain, and Waypoints, and trying to load into ground zero we get stuck after everything is loaded in he gets "waiting for 1 player" and i get "waiting for others to finish loading" and it stays like this for up to 5mins before i close the game, nothing in server logs to suggest an error

both me and my buddy have SAIN, bigbrain, and waypoints installed

we are using a radmin vpn network

force ip and force bind ip weren't enabled when we tried doing it

but it worked without the mods installed

Try force ip and force bind ip again. My understanding is that without forcing it, the game randomly chooses IP from the available network interface IPs on your machine. Use the host's IP in the vpn in both options and only the host needs to do it.

if i'm port forwarding and have upnp enabled would that cause an issue ?

[wooden tapir]

make ur own post

[lime jewel]

You saw through my plan 😂 okay ❤️

[astral prism]

I personally don't use port forward method because it doesn't seem to work for me. My guess that I have CGNAT and getting around that is a headache.

so the vpn route is recommened ?

[astral prism]

Worth a shot. I use personally use ZeroTier for my party. But I also tried Tailscale but it needs a bit more steps to setup. Some other similar programs are Hamachi and Radmin VPN. Pick only one that works for you. The setup for Fika is the same between these VPNs.

We run some mods too and we play fine. If your problem still persists with mods after force IP then I'm out of idea.

From my own limited testing, not forcing IP results in 50/50 chance of connecting and I have 2 interfaces, my eth (to the internet) and my zerotier interface. So it makes sense to me that I force IP to make sure it takes traffic from that. After that I have 0 connection issue even with mods. But your mileage may vary.

ah okok

i think that may be the issue

[wooden tapir]

do we both need to set it

or just host

[astral prism]

Just the host.

[astral prism]

If both set it, the client doesn't seem to affect anything. But if the other guy wants to host, then he has to set it too, using his own IP in the vpn

So only host do it, if host changes, then that host do it. Hope I explain it clear enough lol

FYI, my buddy and I had the same issue and this force bind fix worked for us
