Error 1016 origin DNS error after moving hosts, total beginner here

heads up, once the 1016 is gone you might get a 525 or 526 next. that's the SSL side: Cloudflare is now reaching the new server, but the new server doesn't have a certificate for your domain yet. Install one on the new host (most give you a free Let's Encrypt one in the panel) and set Cloudflare's SSL/TLS mode to Full. also check your MX records if your email ran through the old host. they often get deleted in the cleanup and then mail quietly stops arriving.

1016 means Cloudflare doesn't know where your new server is. Your domain still goes through Cloudflare, but the DNS record inside Cloudflare points at something that no longer resolves, usually a CNAME to the old host's hostname. Fix: 1. Get the IP address of your new hosting account (it's in the new host's dashboard, often under server details or DNS info). 2. Log in to Cloudflare, open the domain, go to DNS. 3. Find the record for the root domain (shown as @ or your domain name) and the one for www. Make the root an A record pointing at the new IP. www can be a CNAME to your root domain. 4. Delete any leftover records pointing at the old host. Usually works within a few minutes. Don't change the nameservers at your registrar for this, the problem is in the records, not the nameservers.
