Invalid Crendtials

I can not login to my account in the Minecraft launcher or Minecraft.net period. I can however connect to Mojang.com

What I expected to happen was...:
I thought I was going to log in and play Minecraft....

What actually happened was...:
When I opened the launcher it wanted me to login again all of a sudden which was strange but I put in my info and nothing, So I decided to change my password but it was to no avail... I still can not connect to Minecraft or Minecraft.net.... I'd really like a fix to this because there is no reason behind why this should be happening...

Steps to Reproduce:
1.Open Minecraft....
2.OR go to Minecraft.net and hit login
