failed to login: null

handguy · May 20, 2023

I'm not sure if this is the correct place to ask for help at, but still.

I'm having a problem with joining multiplayer servers, on version 1.19.4 it just doesn't allow me to click on multiplayer, while on version 1.8.9 it says: "failed to login: null".

I tried the method most people recommended which is to turn on multiplayer in the xbox account settings, but I get the message anyway.

Can someone help me? I'm pretty desperate at this point.

This is on Minecraft by the way.

Hi, I hope you're doing great out there.

I'm an Independent advisor and I'm here to help you with your concern.

I'm really sorry you're having this issue. I found a bug of this issue on the official Mojang page, take a look:

https://bugs.mojang.com/browse/MC-207896

This issue is likely caused by using illegal or incompatible software, which are known to corrupt your hosts list by redirecting any Mojang authentification server address to their own illicit servers. To fix this, you need to remove any non-official software, then you need to fix your affected hosts file by doing the following:

On Windows:

Go to the Start Menu and locate notepad. Right click notepad and select Run as Administrator

Press Ctrl and O on your keyboard, then enter %SystemRoot%\System32\drivers\etc\hosts as the "File name" and press "Open"

Remove every line mentioning "Mojang" and hit save (Ctrl+S).

On Linux and possibly MacOS:

Your user needs to be a sudoer (have administrative privileges), otherwise you need to log as the superuser if you know the password or ask assistance to your system administrator.

Open a terminal application (search for terminal in your application launcher).

Type sudo nano /etc/hosts

Remove any line containing "Mojang" then save the hosts file.

You should now be able to play Minecraft again, please never use any illegal tools or accounts.

It is highly recommended to sign in and change your password.

If your hosts file does not contain any line mentioning a Mojang server or you are still experiencing this issue, they recommend contacting support via the links:

Let me know if you have any doubts. I'll be happy to clarify it.

It was a pleasure interacting with you on this thread. Hugs!
