I changed my username and then tried to get on Minetime. It wouldn't let me on. It said "authentication to minecraft.net failed". Is this even a problem with there server or mojang? Does anyone know anything about this?
I don't know if it was just me or others, I was having some connection issues connecting to the server and forums.
It will be fixed it's just a glitch I would just restart the games maybe once or twice and retry logging back on to the server
"Authentication to Minecraft.net failed" means that you're playing offline. Try getting closer to an internet connection, and restart your game.
Well, it's an internet connection problem. There is no need to reinstall Minecraft, and Emily will not be able to help you, because it's a problem with your connection to the internet.
When you changed your username, did you click "Switch User" on the Minecraft launcher and then sign back in? Because this error tends to happen when you change your username, most commonly because your haven't signed out and signed back in.
