Seamless Serverless Multiplayer Mod FAQ

10 questions players actually ask, answered.

How do I start hosting a multiplayer world?
Open your single-player world, go to the main menu, click the "Server" button, then select "Start Server". The mod will generate a six-digit invite code that you can share with friends.
What's the invite code and how do I share it?
The invite code is a six-digit number that appears when you start hosting. Send this code to your friends through Discord, chat, or any messaging app—they'll enter it in their join menu to connect to your world.
How do I join a friend's world?
Open the join menu in your game, enter the six-digit invite code your friend gave you, and select join. You'll connect to their world as long as you have the same mods installed.
Why can't my friend join my world?
The most common reason is a mod mismatch—you and your friend must have the exact same mod list. The mod checks this automatically and will prevent the join if there's a difference to avoid crashes.
Do I need to port forward or change my router settings?
No. The mod handles all network connections automatically in the background, so you never need to touch your router or learn about port forwarding.
What happens if my internet drops while hosting?
The mod saves your session, so you can rejoin and continue playing. Your friends may be disconnected temporarily, but the world data is preserved.
How long does a multiplayer session last?
The mod automatically closes your session after one hour of no players being online. You can restart it anytime by clicking "Start Server" again.
Can I see how many players are in my world?
Yes. The server interface shows you the current player count in real time so you always know who's connected.
How do I add friends to my friends list?
Open the friends list menu and select the option to add a friend. Enter their player name and they'll appear in your list for easy access to join or invite.
What if the mod crashes when someone tries to join?
The mod is designed to prevent crashes by checking mod compatibility before a player joins. If a crash still occurs, verify that both players have identical mod versions and no conflicting mods.
