Connection is attempted on SSL port with http and failing.

Steps to reproduce

1. Start up Nextcloud AIO in Docker
2. Navigate to https://localhost:8080/containers
3. Submit my.domain for New AIO Instance
4. Receive error "Domain does not point to this server or the reverse proxy is not configured correctly. See the mastercontainer logs for more details. ('sudo docker logs -f nextcloud-aio-mastercontainer')" however DNS is configured correctly and ports are open.
5. Checked the logs.

Expected behavior

Connection is attempted to either https://my.domain:443 or http://my.domain:80

Actual behavior

Connection is attempted to http://my.domain:443 which is an SSL port on a non SSL domain, which I assume is why it fails with the following error:
2023-07-12 12:53:57 NOTICE: PHP message: The response of the connection attempt to "http://my.domain:443" was:

Hi, do you use cloudflare or a firewall that possibly blocks http access on port 443? Because the default domain check indeed uses http on port 443 but that should usually work if there is no external service that blocks this.

I do use cloudflare, I have their proxy disabled, so it's set to "only DNS"
Thanks for pointing me in the right direction! <3

So I've been googling for 30 minutes but am just getting more confused… I'm not trying to do anything fancy or weird. I own a domain I bought through Hostinger, they told me to use Cloudflare to connect the domain to my website. I followed the directions in NextCloud and disabled Cloudflare's proxy.
What do I need to do here? I only want NextCloud on my server, do I need to not use Cloudflare? What should I use?
I am just looking for the simplest and most straightforward setup...

You could try to use a different domain provider

Your suggestion is to change domain providers? That's not a simple setting you can just change.
