Website login fails due to https://ift.tt/1FIqbOr hitting status 400 error

Greetings all the I am trying to log into to the website world.wallstreetenglish.com, however logins fail on occasional laptops of our students because of the XHR track hitting an error message 400.

Other laptops are fine and the track POST goes with fine.

I tried turning off firewall, defender and any other security measures that may be blocking it, when I compare the header info with another header info that works (On another laptop) they are the same.

Please help.
