If this is happening to you it is because Mojang has blocked your account. Please contact Mojang support about this and give them your account ID. Tell them about what happened. It will probably take one week to get your account unblocked. This video is an example of this before I was unblocked. Go to mojang.com/support. This might also be because you haven't signed out and signed in to your Minecraft launcher after you changed your user name. By contacting Mojang support my Minecraft account is now unblocked and I can login to Hypixel. UPDATE - If you have downloaded MC Leaks this might be the reason why you are blocked due to it being a third party website. RE DOWNLOAD MC Leaks and run it, instead of press the MC Leaks button, click the Mojang button. Then close the MC Leaks launcher and uninstall it.
