I purchased a domain from Namecheap and connected it to my Cloudflare account. I then added a new nameserver for my hosting service, serv000.com, in the DNS records on Cloudflare. However, when I add the DNS records to both serv000.com and Cloudflare, nothing happens. Even after waiting 48 hours, the DNS records are still not active. I have ensured that the DNS settings are added to both the Cloudflare dashboard and my serv000 hosting panel, and my SSL protection is set to full ( I changed it to flexible and nothing changed) . What steps should I take to resolve this issue?
