'Failed to login: Invalid ip' when connecting to servers

Question

When I try to connect to a minecraft server, it says

Failed to login: Invalid ip 123.123.123.*

Giving me my IP address with the last octet asterisked out.

Now the Minecraft launcher forgets my logged-in accounts, which is unusual.

---

Now I can't log into the launcher nor the website, Mojang tells me I have an invalid email or password.

Answer 1

For stuff like this, I always head over to the Mojang Portal. This way you know the information is authentic and current.

In this case, 18 minutes ago, in their twitter feed, they posted:
