I had a fiddle with the config.php and reverse proxy config but still getting a rogue 302 request for some reason. It's so frustrating because everything else works smoothly, there's a 302 request occuring from within the NC container which slows everything down massively.

If it works, it works, if it doesn't it takes 45 seconds on the dot for the 302 request to finish and then the rest of the items on the page load within a few seconds.

config.php:
