What DDNS providers you guys recommend?

I'm new to self-hosting. All I did so far was install Ubuntu Server, enable SSH and tried setting up DuckDNS, which I could not set up automatic update of my IP following the documentation, neither updating manually through the website, which even though seems to be changed, when I ssh the domain, I get the initial IP

Anyone using DuckDNS? Is it working properly for you guys? Did I just mess something up?

What other DDNS providers would you recommend me?
