I have tried everything possible, using the most accurate AI that I could find after trying all the best and most popular options. Chat GPT 5+ has done everything perfectly for me the first try after all other AI gave me error loops forever.
5 + discerned that it is not actually possible to create an Auto-Rejoin mechanic without using third party tools that are very much against Roblox’s rules. I found an example of the tools that would actually work at this point, after many updates to prevent people from circumventing the 20 minute kick for inactivity mechanic. ChatGPT dissected it and said it was as absolute amalgamation of everything one could possibly find to break Roblox’s rules.
I gave up after we tried everything possible and it gave me a very confident response and exact detail how and why nothing works unless you use 3rd party tools that break the rules.
But I was left wondering, why do I see so many Roblox games that are very popular and have many active players that use this Auto-Rejoin mechanic if the only possible way anymore is by using very against the rules tools that do many things Roblox does not allow?
Am I actually missing something here? I asked the assistant in Studio as well but it gave me an answer that GPT 5+ said would not work for very many reasons, especially after all the updates to prevent people’s attempts to get around the 20 minute inactivity kick. I looked around this forum and I tried many things I could find on the topic but all of them have been updated to not work anymore. But yet I still see all these games with Auto-Rejoin mechanics.
Please help me if I am missing something, and please I have absolutely no desire to break the rules, at all. I put way too much hard work into learning the Studio as a completely new Developer just to make this dream project come to life, but I really wanted an Auto-Rejoin mechanic like the other games in this genre that I play have.
I wonder if there is a completely 100% allowed way to create an Auto-Rejoin mechanic currently? Or if all the games that have one now are using third party tools against the rules?
Just teleport the user back to the same server using TeleportService before they spend 20 minutes being inactive. This is how all games do it (if you pretend to be afk you can see the teleportation being done in action).
There’s a limit on how many times you can teleport the player back in but if you only teleport them when they’re inactive for a while (lets say 15 minutes) and not on small intervals you will never reach it.
Thanks for the reply. Unfortunately that is what I focused on for about 13 different attempts total that didn’t work in different setups using the same theme. Here is what I have tried, summed up very concisely using ChatGPT that helped me set all of these up (the one that has been successful doing everything else on it’s first try until now):
Everything We Tried — Bullet-Point Summary
1. “Teleport Before Idle Kick” Method (the one the forum guy suggested)
Server-side PlayerAdded trackers teleporting after X minutes
Client-side countdown before teleporting
RemoteEvent-triggered teleport after inactivity
Variants using task.wait(), while loops, RunService, BindToRenderStep
Result
ALL FAILED — the player is kicked before the teleport fires or Roblox blocks the teleport because:
Teleporting does NOT reset idle kick anymore (Roblox patched it).
You cannot bypass inactivity using teleport — client stops responding.
The idle-kick screen halts client scripts, meaning the teleport can’t fire.
Roblox rate-limits and rejects self-teleports when idle.
This is exactly the method the forum person is suggesting And it is literally the first thing we tried 13+ different ways And it is patched, dead, and impossible now.
2. “Detect Idle by Character Movement & Teleport at X Time”
We tried:
Humanoid.Running event
Humanoid.Jumping
Heartbeat distance tracking
tick() time-since-last-movement logic
Result
Failed, because:
Idle detection works, but teleport still doesn’t save you.
At ~18–19 minutes the client is soft-frozen internally.
Teleport request never completes before shutdown.
3. “Rejoin Using Error Prompt Detection”
Using GuiService.ErrorMessageChanged:
Detect when the user is disconnected
Auto-rejoin loop on error
TeleportToPlaceInstance inside a retry loop
Result
Failed, because:
Idle disconnect does not fire an error code exposed to GUIService.
The client is fully shut down before any script runs.
4. Auto-Rejoin Scripts Found on DevForum
Result
Failed, because:
The shutdown sequence for idle closes Lua VM instantly.
No script survives long enough to rejoin.
5. “AFK Prevention by Fake Input”
We attempted to explore:
Fake Humanoid movement
Fake platform standing
Mini animation flickers
Anchoring / unanchoring
Camera shaking
Applying forces
Result
All blocked
Client idle detection does not use avatar motion anymore.
Roblox listens for user input, not world movement.
Is there a way I messed up all the different versions of the TeleportService approach I tried? Does anyone actually have a currently working version of that setup for Auto-Rejoin? Does anyone have any version working at all that is 100% within the rules?
I have looked at the Developer Console within games that use the Auto-Rejoin mechanic and concluded that you were absolutely right I was just doing it wrong and I must thank you for the help. This time it has worked, and I am not the brightest individual so I will copy paste the summed up version of what worked this time from ChatGPT:
In short:
We solved it by avoiding the disconnect entirely, not detecting it.
A clean idle-timer + scheduled TeleportService is all that’s needed, with no UI or heartbeat magic.
Very happy to have a working Auto-Rejoin that is completely within the rules.
