What is the name of the domain?
What is the issue you’re encountering
I am going slowly crazy. I first set up Dynu DDNS to reach my self hosted website. It worked fine, but I decided to change to Cloudflare for better security. I wrote a script that updates the public IP address in the DNS setting of Cloudflare and it works fine. I did delete my Dynu account, I added the Cloudflare NSs to my registrar, I made sure the DNA record is pointing to my actual public IP as a A record and not to Dynu using CNAME. I purged caches, I restarted router and server. But when I use my phone on 5G to access the website, it still is pointing to a Dynu Parked Domain website. How is this possible? I am at my end.
