Have lost access to my website and wpadmin, website not secure

Hi,

I have had problems accessing my website. On wp-admin, I tried to alter the URL to https and in doing so, I lost complete access.

The website was created using profree host and domain name is on GoDaddy. I have pointed the nameservers to ns1.byet.org and ns2.byet.org to regain access, but it doesn't seem to connect.

I am trying to create a new website with a custom domain beaconofunityafrica.com it says that it is not available.

I don't have an SSL certificate yet, but need to regain access to my website.

The website URL is beaconofunityafrica.com

Can anyone help?
