So theoretically you can unlock your nokia 8 but the problem is that the page where the process starts (where you acknowledge the risks and sign up) is messed up entirely.
There's none until hmd fixes its website (which will likely take way long). I can see in the console that css and js are showing 404 errros. Css could be avoided, but the necessary js is needed to complete the ajax login.
