Minecraft multiplayer doesn't work? - 2

I bought Minecraft 3 years ago and played multiplayer.

But then the password didn't work and I used Mc Leaks: mcleaks.net/contact

So that I could play Minecraft again. But that became too cumbersome for me and I bought a real acc. When I log on to my new acc and went to a mutiplayer server, there was this error code, see the first picture.

I uninstalled and reinstalled Minecraft

Then I went to the MC Leaks page and there you had to switch back to mojang see second picture:

But nothing happens.

Can you help me?

You need to uninstall MCleaks

I've already

So for me it was because it had the same error

In the second picture, MCLeaks is selected.

Click on Mojang - it should then turn green.

Then close your Minecraft and your launcher. Start the launcher. Log in again.

I'm not sure if i deleted it how do i find the mc leaks file

Yes, I think you had to select it before deleting it. I think so with me

No does not help

You know you have to download the authenticator to click Mojang, right?

I did

I see. It doesn't look like this in the picture (because of the background color).

This is a different picture but I put it from monajng

Did you quit your antivirus while using the authenticator?

What is authenticator

That: https://mcleaks.net/authenticator

Yes
