Among Us error codes
The game you tried to join is full. Check with the host to see if you can join next round – The game could be full, or this could be server shenanigans. The game might not be full, but it might take you half a dozen tries before you can successfully join. If you’re playing with friends and know the lobby still has room, just keep trying.
The game you tried to join already started. Check with the host to see if you can join next round – Again, the game could already be in-progress, or Among Us could be lying to you. If you’re playing with friends and know the game hasn’t started yet, just keep trying to join until you get in.
You disconnected from the server. Reliable packet 1 (size=#) was not ack’d after #ms – The Among Us servers are down or under heavy load. Keep trying to connect, change server regions (click the globe icon in the bottom-right corner) or wait a bit before trying again.
You disconnected from the server. Could not send data as a SocketException occurred: Network is unreachable – According to Redditors, the mobile version of Among Us returns this error when trying to play on a Sprint data connection. Connecting to Wi-Fi will hopefully solve the problem.
The Among Us matchmaker is full. Please try again in a few minutes! – Too many people are trying to play. You can try changing server regions (click the globe icon in the bottom-right corner) or just wait out the rush.
You disconnected from the server. Sent # pings that remote has not responded to – This means the server is having trouble reaching your client. Ensure that your internet connection isn’t dropping packets, especially if you’re on wi-fi. Running a speedtest can help determine this. If your connection is fast and stable, chalk it up to another server issue.
Forcibly disconnected because: ReliablePacketWithoutResponse – Less common than the “reliable packet” error above, but the same advice applies. This is likely a result of the game servers being overloaded, so trying repeatedly to join is likely your best option. Alternately, run a speedtest to ensure your connection is stable.
