Players getting stuck infinitely mid teleport

Our game has a custom loading screen between teleports. According to our poll results, around ~25% of people (around 10k ccu average) are sometimes or multiple times getting stuck during the teleport. They have said that they arent able to press escape to open the roblox menu at all, meaning it’s getting stuck somewhere during the internal teleport. We have checked error reports, but they havent given us much of an idea of the underlying problem.


Our game uses a teleport system made from the approach of the safe teleport handling example on Teleport between places | Documentation - Roblox Creator Hub.

Expected behavior

The teleports should not infinitely get stuck and people should teleport into the place.

We believe it mostly occurs during teleports to the places prefixed with Queue_, but it has not been limited to these places.

I myself have also experienced crashes during teleports and some players have reported this aswell.

Hey there!

Unfortunately, we don’t have enough information from your report to locate the cause of this issue.
Could you please provide more information, like the crash log or error reports you mentioned, a video or some other thing that would help us investigate? I tried to reproduce this issue within the experience myself but wasn’t able to.

If you need more info about which info/files might be useful for us and why, check the How to post a Bug Report.

We’ll stay tuned for your answer.

Thanks for understanding.
Have a Nice Day!

Thanks for the response! I was hoping you would be able to see some internal details that we’re not able to see, but here are the error logs filtered with Teleport in them. They haven’t been of much help, though.


It’s a bit hard to reproduce since it’s inconsistent but players have reported that it has started happening after a couple of matches played. They will get stuck on the custom loading screen provided in the main post. For now though, we’ve disabled the custom loading screen in hope to get more information.
Sadly we don’t have any videos of it at the moment but I will be trying to get one. Is there anything else I could do to help you track it down?

Just got another report and it seems to be either the Failure error or the Game 312 one?

I’ve been able to get 2 clips of the issue so far.



Code for the TeleportInitFailed event:

TeleportService.TeleportInitFailed:Connect(function(player, teleportResult, errorMessage, placeId, teleportOptions)
    self._notificationService:Push(player, {
        Duration = 15,
        Message = "That's no good. We're going to try that again...",
    })
    if teleportResult == Enum.TeleportResult.Flooded then
        task.wait(FLOOD_DELAY)
    elseif teleportResult == Enum.TeleportResult.Failure then
        task.wait(RETRY_DELAY)
    else
        -- if the teleport is invalid, report the error instead of retrying
        warn(("Invalid teleport [%s]: %s"):format(teleportResult.Name, errorMessage))
        self:_OnTeleportFailed(player)
        return
    end

    self:_TrySafeTeleport(placeId, { player }, teleportOptions)
end)

Code for the _TrySafeTeleport method:

function TeleportServiceServer._TrySafeTeleport(self: Types.TeleportServiceServer, placeId: number, players: { Player }, options: TeleportOptions): boolean
    local attemptIndex = 0
    local success, result -- define pcall results outside of loop so results can be reported later on

    repeat
        success, result = pcall(function()
            return TeleportService:TeleportAsync(placeId, players, options) -- teleport the user in a protected call to prevent erroring
        end)
        attemptIndex += 1
        if not success then
            task.wait(RETRY_DELAY)
        end
    until success or attemptIndex == ATTEMPT_LIMIT -- stop trying to teleport if call was successful, or if retry limit has been reached

    if not success then
        warn(result) -- print the failure reason to output
    end

    return success
end

All teleports are initiated using the _TrySafeTeleport method.

Clip of the teleport taking over a minute and then failing:


Clip of the teleport taking over a minute, failing but working on 2nd attempt. The issue is that most people will have left before the minute mark.

I have more clips but they’re the same error as the ones above, also taking up to a minute.
