Absolutely! From my own experience, I ran into a similar issue as you are dealing with right now. My problem was that I had forgotten to enable the host header in my request. There’s an easy fix though – just head over to the headers tab and make sure the host header is enabled. If you can’t spot the default headers there, there will be a button you can click to make the default headers visible. Once you’ve done this, you should be all set!
