how to find my hosting provider
If you are using Cloudflare, when you log in and go to ‘DNS’, you should see the DNS records for your site. You may see a hostname there that can help you identify your host, or you could lookup the IP address with a tool like https://www.ultratools.com/tools/ipWhoisLookup and see if that helps.
You could also check back through old emails and/or invoices from them.
