NoReverseMatch at /login/ (Django) - django

Question

I'm getting a NoReverseMatch error at login/ , when it redirects to profile.html , if i login through other pages where it redirects to another page, then it works fine , but when I click on the login button which redirects to the profile.html page , I get the NoReverseMatch error. Do you know what is wrong in this code ? , I can't seem to find the fault.
