Http issue of request denied

I need help with this so what it does is simple I make a Python server and Roblox uses HTTP to request from it if a person presses the execute button on the server. which will run whatever is on the python server textbox. Simple right? it works just fine on Roblox Studio but if I go into a game I get a Request Denied.

Here is the code for it:

Roblox Server-Sided Script:

local HttpService = game:GetService("HttpService")
local url = "http://localhost:5000/poll"

while true do
	local response = HttpService:GetAsync(url)
	local data = HttpService:JSONDecode(response)

	if data.command then
		local func, err = loadstring(data.command)
		if func then
			warn("Error in executing command:", err)


Python Server Code:

from flask import Flask, render_template_string, jsonify, request

app = Flask(__name__)

commands = []

<!DOCTYPE html>
    <title>Execute Command</title>
        body {
            font-family: Arial, sans-serif;
            display: flex;
            justify-content: center;
            align-items: center;
            height: 100vh;
            background-color: #f5f5f5;
        #commandInput {
            width: 400px; /* Adjust the width as needed */
            height: 150px; /* Adjust the height as needed */
            font-size: 16px; /* Adjust the font size as needed */
            padding: 10px;
            border-radius: 5px;
            border: 1px solid #ccc;
            margin-bottom: 10px;
            resize: none; /* Prevent resizing */
        button {
            width: 100px;
            padding: 10px;
            font-size: 16px;
            background-color: #4CAF50;
            color: white;
            border: none;
            border-radius: 5px;
            cursor: pointer;
        button:hover {
            background-color: #45a049;
        function executeCommand() {
            var commandInput = document.getElementById('commandInput');
            fetch('/execute', {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json'
                body: JSON.stringify({ command: commandInput.value })
            .then(response => response.text())
            .then(data => console.log(data))
            .catch(error => console.error('Error:', error));
        <textarea id="commandInput" placeholder="Enter text"></textarea>
        <button onclick="executeCommand()">Execute</button>

def index():
    return render_template_string(HTML_TEMPLATE)

@app.route('/execute', methods=['POST'])
def execute():
    command = request.json.get('command', '')
    return f"Command '{command}' added to queue"

def poll():
    if commands:
        command = commands.pop(0)
        return jsonify(command=command)
    return jsonify(command=None)

if __name__ == '__main__':'localhost', port=5000)

For further info about the error I got this screen shot it might help.

Well that is because localhost:5000 is not a valid web server on Roblox’s end. Running servers on Studio are running on your client.

oh okay then ill try to upload it to a website instead
