Me and my buddies thought it would be funny to play Minecraft again. While the others could log in without problems (also on my account), I had and have the problem that I can't log in. I also tried to log in to other Acc's without success. On the computer of my brother, I can log in without problems… Only on my not. Now the question: What should I do or what can you do there?
Are you talking about signing in to the browser or the client when logging in?
The best thing to do in the browser is to go to the page and hit Ctrl + F5. Possibly. Does that help, otherwise try another browser or delete your cache and cookies (how to do that you can quickly find out about Google).
When it comes to the client / launcher is recommended first, a new installation, preferably via the Control Panel - All Programs (For Win10 Settings - "Apps")
By both. That's the problem. First it was just in the launcher. Then I wanted to reinstall it. Have minecraft uninstalled on the side and I could not log in anymore. Page reloading also already tried. Unfortunately, everything does not help anything else you have an idea?
Try again later, Mojang now and then IP / MAC lock, which should be up in 24 hours.
I had it too. Go to the mojang page and change the password to the same one and close minecraft then open it again
