I'm currently unable to login to account.mojang.com - I receive an error that's displayed in the attached screenshot. I've completed the following troubleshooting:

• Different web browsers
• Different computer
• different external IP
• Different device (tried PC, Android Phone and Android Tablet). 

In each case I get the same error, which stops me from being able to login an manage my account. I've raised this issue with the Minecraft help service desk, and they pointed me in your direction, as they no longer seem to be able to help.

Thanks,

Paul
