Joining a Foundry co-op game: connection and bugs

A friend has set up their Foundry factory and dropped you an address: all that's left is to join and start mining together. The good news is that connecting takes three moves. The bad news is that a single comma out of place in the IP is enough to block everything. Here's how to get in cleanly, and what to check if the game turns you away.

Step 1: get hold of the address

Two pieces of information are enough: the IP and the port, supplied by the game's host. On a Fly-Serv server, that address shows up in FlyPanel as soon as it's delivered, ready to copy-paste and send to the group.

Step 2: the in-game direct connection

In Foundry, open the multiplayer menu and choose the direct connection: paste the IP and the port, confirm, and you're in the game. If the factory is locked, enter the password set on the host side in DedicatedServerConfig.json.

Step 3: when the connection refuses to go through

• IP and port: reread them character by character, a typo is cause number one.
• Password: copy exactly the one you were given, capitals included.
• Game version: client and server must be on the same Foundry build.
• Server actually on? A self-hosted server can be switched off; on a server hosted at Fly-Serv, it stays online 24/7.

Almost every failed connection comes down to three suspects: a mistyped IP, a wrong port, or a client and a server that aren't on the same version.

And what if it were your turn to host?

Fancy creating your own game and inviting the crew rather than joining someone else's? Launch your Foundry server with Fly-Serv from 3,99 €/month: instant delivery, an address ready to share, Anti-DDoS included. To start off right, follow our guide to creating a Foundry server.
