    minecraft network protocol error 1.21.1

    Hi there! This is Virginia O.

    I understand that you are experiencing issues playing Minecraft.

    I apologize for the inconvenienced this has caused you. I will do my best to help you.

    Please verify Minecraft installation by launching Minecraft without mods to see if the issue persists. To do this, open Minecraft Launcher. Select the latest vanilla version (no mods). Start the game and check if the error still appears.

    And then check internet connection & server compatibility. Make sure that the server version matches Minecraft 1.21.1. Here are the steps, restart your router.

    Switch to a different Wi-Fi or mobile Hotspot. If using a VPN, disable it temporarily.

    If the issue persist after performing the troubleshooting steps, a clean installation is needed by uninstalling Minecraft Launcher. And then reinstall Minecraft from https://www.minecraft.net/en-us and try launching the game to see if it works.

    Thank you for your cooperation.

    Minecraft Network Protocol Error

    Hi, my name is , I'm an Independent Consultant and a member of the Xbox community like you.

    Check if the error occurs in other versions, as you are trying to use mods, the best thing to do is contact the CurseForge forum where they can help you better.

    You can also try contacting Minecraft support;

    Getting Network Protocol Error when trying to join (removed) server

    Sorry we cannot assist with illicit copyright violating servers
  6. Faline C Win User

    I can't play multiplayer on bedrock edition it keeps loading and then says "disconnected from server" ISP - JIO 5G (INDIA)

    Hi Dev, thanks for reaching out for help here on the forum. I'm sorry to hear you're dealing with problems getting into multiplayer with Minecraft Bedrock.

    Do you see the same error anytime you try to join a server, or does it only affect one specific server?

    Your network might have strict NAT settings or high latency affecting Minecraft multiplayer. If you're using a VPN, temporarily disable it. Try switching to a different network, or checking if your ISP allows port forwarding for better connectivity. Also, make sure your the launcher is up to date.

    I hope this helps you start troubleshooting. Let me know if you have any questions!
