502 bad gateway against a site

[jeremyfiel]

I was looking at www.maersk.com and i'm getting a 502 bad gateway in console. they do indeed have a css file in their assets directory

I have the same issue, here is what is returned from the request

An error occurred with this application.

NO_STATUS_CODE_FROM_FUNCTION

The website is up, it is a multiple page app with only one CSS. I can DM you the link.

Edit

So it worked for me when I removed https and www. I checked the domain works with https and with www. From the top of my head, it is probably redirects that are making a problem.
