Among Us Impostor Server Ports: UDP 22023 and Connection Checks
If players cannot join your Impostor server, the port is the first thing to check.
Default ports
Impostor listens on port 22023 by default. Game traffic uses UDP on that port. Newer versions also provide an HTTP matchmaker, which uses TCP. In recent versions it is commonly on the same number, but older ones used a separate port, so check the Console on startup to see what your version reports.
- 22023 UDP for game traffic
- TCP for the matchmaker, per your version
On Tabi Cloud the allocated port is shown in your panel. Use that in your region settings.
Match the config
The port players use must match PublicPort in config.json. If your panel assigns a different port than 22023, set both ListenPort and PublicPort to suit and restart.
Checking it works
- Start the server and watch the Console for a line showing it is listening.
- Add your server as a custom region in Among Us using the IP and port.
- Try to create a game.
If the game hangs on connecting, the port or IP is likely wrong.
Common mistakes
- Using the wrong port in the region file
- Putting 127.0.0.1 in PublicIp
- Forgetting UDP, only allowing TCP
- Editing config.json without restarting
Clients
Custom regions are normally set up on PC with a region installer or by editing the game's region file. Support on other platforms varies, so check the Impostor documentation for your device. Ask on Discord if you are unsure.
