Hello
You must first find the company that hosts your site, which you can use at https://intodns.com
Then correspond with the host company of your site and send documents to the company as the administrator and manager of this site, such as the domain panel and its options (send a screenshot, of course) and anything that shows you are the owner of this site.
After checking, the host company confirms it and you can create a new account on that company’s site, your hosting account will be transferred to you from the previous manager and you can pay your service invoice and your website will be reactivated immediately. .
Good luck
