How do I actually get to the nextcloud app, after setting up with cloudflare?

Hello, so I set up Nextcloud AIO on an Ubuntu server. I exposed it publicly using Cloudflare zero trust tunnel, and it works. When I go to the domain it brings up the AIO page, but when I click “open your Nextcloud” it just loads endlessly. Does anyone have any idea what I’ve done wrong, where I can go from here? Anything is appreciated. Thanks.

Hi, did you follow all-in-one/ at main · nextcloud/all-in-one · GitHub step-for-step?
