Can't log into Minecraft Launcher, Minecraft.net or Mojang?

So after 2 weeks of not playing Minecraft, I wanted to try playing again but somehow when I opened the launcher it asked me to log in again, so I entered my email address and my password - error. I tried to log in on Minecraft.net, "username/password is wrong" error. Same on the mojang website. I pressed on the "password forgotten" on the launcher, changed my pw and tried again - nothing.
I pressed on I forgot my password on Mojang, Minecraft.net and the same happened. I tried to log in with my username AND my email, I tried both and there was no success.
