This may not solve your immediate problem, but ever since I've been using Google Sites I buy/manage all my domains on Google Domains.
I've had similar issues with connecting my domains through other providers. I just transferred all the domains I owned to Google Domains - now everything is more straightforward.
If you decide to transfer them over - you can just follow these steps to connect your site.
The key step is to "Verify ownership of your domain" through the Google Search Console.
I hope that helps!
Well done!

About This Website is hard to read on my browser as there is not enough contrast.
The site is a bit busy which is fine but I found it difficult to separate the page into clear sections and it blurs a bit together for me as a new user. Try to keep the home page for the most important information that any person visiting needs to know. Then put everything else under other tabs as needed.
I hope this helps and keep up the great work!
If you know the user is using Gmail, you can use this kind of link. They would still need to hit send though.
