Unable to launch local test server due to constant disconnect

Bug Reports Studio Bugs

For some reason everytime i launch a local test server the clients instantly disconnect with Disconnect from UNASSIGNED_SYSTEM_ADDRESS

steps to reproduce:

  1. launch a local test server with 2 players or modify network settings to include some latency and launch.

game affected: Plane Crazy | Play on Roblox

– Edit it seems the issue was because of the playeradded function instantly kicking the player.
However it seems instead of showing the correct disconnect message it shows either a random message or closes the clients instantly which makes it really hard to know whats actually going on.

While the main post seems to have been updated with a fix for their specific cause, there are still many people like me who run into this issue seemingly out of nowhere – even idling in studio for 5 minutes will result in a disconnect with this error. It’s not consistent yet still extremely frequent to the point it makes certain studio work impossible.

I’ll send a log to the group you mentioned.
You’ll be able to do a string search for the occurrence UNASSIGNED_SYSTEM_ADDRESS which appears here.

Here are all related reports on this error.
