In my game I have a lobby where players can step on a pad and it will teleport them to the main game. Randomly throughout the day a server will experience a Teleport to Reserved Server failed: HTTP 400 (Bad Request). After that happens the game completely breaks and players are no longer able to be teleported anymore. I’m unsure as to why it wouldn’t just restart the countdown and try teleporting again. (I have tried using Roblox’s Safe Teleport module on their wiki and that didn’t work either).
I provided screenshots and the code down below. Thanks!
pcall(function()
local success, code = pcall(function()
return TeleportService:ReserveServer(DESTINATION_PLACE_ID)
end)
if success and code then
lobbyInfoPart.Status.Ready.Text = "Teleporting Players..."
local teleportOptions = Instance.new("TeleportOptions")
teleportOptions.ReservedServerAccessCode = code
local success1, result1
success1, result1 = pcall(function()
return TeleportService:TeleportAsync(DESTINATION_PLACE_ID, readySoloPlayers, teleportOptions)
end)
--SafeTeleport(DESTINATION_PLACE_ID, readySoloPlayers, teleportOptions)
else
print ("Failed to Teleport Player")
end
--[[local reservedServerCode = TeleportService:ReserveServer(DESTINATION_PLACE_ID)
local teleportOptions = Instance.new("TeleportOptions")
teleportOptions.ReservedServerAccessCode = reservedServerCode
SafeTeleport(DESTINATION_PLACE_ID, readySoloPlayers, teleportOptions)]]--
end
Hi, is this still a problem you are facing? Could you please expand a bit more on your game breaking. Is it that the player is unable to trigger teleport again if they step on the pad in your game/how do you trigger this pcall? Thanks!
Hey thanks for following up,
I started from scratch and had it recoded with help from what it was before. I am still unsure why my previous code didn’t work. It is triggered by a timer that counts down and once there are enough players in the game it will call it. I can post the entire script here if you’d like to take a look. With my new teleportation system however, I am not getting the error anymore. I asked a lot of people and tried looking up reasons to why it might have been happening but I couldn’t find anything. It doesn’t happen anymore but I am curious as to why it was with my old code.
Also, once it broke the teleporting had gotten stuck on lobbyInfoPart.Status.Ready.Text = “Teleporting Players…” and didn’t go back until shutdown.

Hi, it actually just occurred again for me today and broke another server. The code is completely different to see if that was the problem and it’s still giving the same HTTP 400 Error. I shut down the server so it fixes but when it happens at night and I’m not on people can’t play my game.
Hey @Randy_Moss, we recently rolled out a fix that should help in the case of teleporting groups of players to reserved servers. Are you still seeing the issue you described?
Sorry I should have mentioned it before but I would get both. The screenshot only showed 400 but it would be different every time it happened. I believe the 400 error was more common though. I just checked one of my severs right now and got another 400 error as well.
I opened a bug report on this same issue. These 502 errors bypass pcall/xpcall and if called inside a task, will indefinitely suspend the thread at the next yield.
My temporary hacky workaround was a separate monitoring task that monitors when my Teleport task dies, it calls coroutine.resume() on the thread.
