Hi,
If you try to do a url-retrieve over HTTP on a URL that requires HTTP
basic authentication, and you have an .authinfo file, and that .authinfo
contains an incorrect login, then Emacs will keep appending the same
Authorization: header to the request -- over and over, making the
request larger and larger, with no stop condition. Eventually nginx
produces a "400 Bad Request" error because there were too many headers.
Emacs should instead error after the first attempt at authentication
fails.
$ emacs --version
GNU Emacs 25.2.1
Andy

I'm able to reproduce this with this in my .authinfo file:
machine jigsaw.w3.org:443 login guest password wrong
and then:
(url-retrieve "https://jigsaw.w3.org/HTTP/Basic/" #'ignore)

And this should now be fixed on the Emacs trunk.
