Hi Freddie,
Sorry to hear about that. Are you using a VPN or similar service for your connection? In that case you could try without it.

I can log in through my phone's tethering but when I use my main internet connection it comes up with "Invalid username or password". This is in the launcher and on Minecraft.net but if I try on my phone it works fine.

I now use OVH and it is working fine however I wonder where they are going with this... I hope it's not another Netflix.
