Connectivity Problem with Minecraft - Can not join the Server

Alright, no worries—let me break it down step by step for you!

Quick External Test with Python :snake:

  1. Install Python (if it’s not already installed):
    On Ubuntu, run this command:

    sudo apt update && sudo apt install python3

  2. Run a Simple Web Server:
    Go to any folder on your server with:

    cd ~

    Then start a lightweight web server on port 8080:

    python3 -m http.server 8080

  3. Forward Port 8080 in Your Router:
    Just like you forwarded port 25565 for Minecraft, forward port 8080 to the same internal IP of your server.

  4. Ask a Friend/Tester:
    Share your public IP like this: http://yourpublicip:8080
    Have someone outside your network plug it into their browser. If they see a basic webpage of the folder contents, the connection is working.

  5. Stop the Server:
    Once done, stop the web server by pressing CTRL+C in your terminal.

If they can connect to this simple server but still can’t connect to Minecraft, it’s clearly some Minecraft-specific config headache. If they can’t connect at all, we pin it down to your network. Let me know how it goes! :glowing_star:
