Why do I get this teleportation error when I try to join someone's game with a script?

I've been trying to build a script to join one of my friends' games automatically.

What does my script do?

First, it searches through my friends list and checks if the player I chose is playing a game and is on my friends list. Then, it tries to join that server.

What is the problem?

This script is not giving me any syntax errors, but when I join the game (NOT IN STUDIO), it says this:

Teleportation Failed

Attempted to teleport to a place that is restricted. (Error Code: 773)

It gives me this error every game. Is this a Roblox issue or am I doing something wrong?

Here's the script: (this is a local script)

local player = game.Players.LocalPlayer

local teleportService = game:GetService("TeleportService")

local onlineFriends = player:GetFriendsOnline(200)

script.Parent.MouseButton1Click:Connect(function()
	local playerToFollow = script.Parent.Parent.TextBox.Text
	
	for i, v in pairs(onlineFriends) do
		if v.UserName:lower() == playerToFollow:lower() then
			if v.IsOnline or v.LastLocation then
				print(v.PlaceId)
				print(v.LastLocation)
				print(v.GameId)
				foundUsername = true
				teleportService:TeleportToPlaceInstance(v.PlaceId, v.GameId, player)
				break
			else
				print("Couldn't teleport because: "..playerToFollow.." is not online or is not playing a game.")
			end
		end
	end

	if foundUsername == nil then
		print("User '"..playerToFollow.."' is not on your friends list.")
	end
end)

How can I fix this? Any help/advice is appreciated! Thank you! - Green_Lime2

It happens bcause you're trying to teleport to a place which either:

• belongs to another game and isn't its main place (so it's protected from foreign teleports)
• is a private server created by the game
• is a vip server

You can't teleport to those and there is no way to "fix" that
