502 webserver error

Try https://mcp.microsoft.com (without the www.) Login works fine from there at the time of writing this post.

Me too, I also get the "502 - Web server received an invalid response while acting as a gateway or proxy server.". No matter what address I type in. And it is so for the whole week. I can't even get to my transcript (this is what I want to access).

I use Windows 10 Enterprise, IE 11 or Edge, same problem. 

I just logged in without any problem (except that it is very slow). It worked from IE9, IE10 and Chrome.

Also tried to login with other browsers and with the link https://mcp.microsoft.com 

But, I get the same error, 502 web server error.

Please help.
