How to check that friends can join your Project Zomboid server

The card Can my friends join? on the Overview page checks your Project Zomboid server the way a friend's game would see it: is it running, are the ports right, which build players need, are the mods downloaded, is there a free slot. Type a friend's username to check their account and bans too. Each problem has a button to the page that fixes it.

Run the check

1. Open your server in the panel and stay on Overview.
2. Find the card Can my friends join?. It runs once when you open the page and shows a verdict: "Your friends can join.", "Your friends can probably join. Read the notes below." or "Your friends cannot join yet."
3. To check one friend, type their name in A friend's username (optional) and click Check this friend. The card says "Checked for" and the name.
4. Click Run again after you fixed something.

What each row means

The friend rows

• "<name> has an account on this server." If they typed it differently, the card says how it is spelled: "they must type it exactly like that."
• "<name> is banned on this server." Lift it on the Players page, Bans tab: How to unban a player on your Project Zomboid server.
• "<name> has no account, and only players with one can join." Add them on the Players page.
• "<name> has not joined yet; they can." The game makes their account the first time they join.

Good to know

• The check reads your server's files, so it needs the permission to read file contents. It is hidden while the setup wizard is open.
• It cannot see your friend's own computer. If every row passes and they still cannot join, go through Players cannot join your Project Zomboid server.
• The card's fix buttons are Start server, Open Players, Open console, Open Network, Open Settings and Open Workshop.
