Port 443 error when installing

Hey all. So I did some research on this error for the past couple hours and can’t seem to figure it out.

I’m using a Hetzner plan and have gone through with adding mailjet DNS to my cloudflare. I’ve also turned off the orange clouds and they are now gray. Still seeing the same issue.

Not sure what I could be missing here honestly. I chose to not use a custom hostname like example.mysite.com and to use my root instead, but I don’t think that would cause this issue would it?

Thanks

Does your domain name resolve to the ip address of your server? Does the server have some other web server running?
