I had a droplet on DigitalOcean and had the old IP routed through CloudFlare. I had an issue with the server on Digital Ocean and had to delete it. I created a new one on Digital Ocean and configured the new IP on CloudFlare. However Cloudflare is still pointing to the old IP as it still shows me the error that is related to the old server IP. I purged the cache on CloudFlare and it still points to the old one.
I am not sure what is happening as I configured the DNS to the new IP here on CloudFlare.
