Intall error : How to solved "too many requests of a given type..."?

Hi guys,
Sorry for my bad english…
I created a web server with my new Raspberry Pi 3, and I’ve used openssl to get HTTPS website adress, but Google block the acess to my website because it’s a self-certificated site.
So I’ve tried to install Let’s Encrypt but during the installation, I’ve got an error :

An unexpected error occurred:
There were too many requests of a given type :: Error creating new cert :: Too many certificates already issued for: no-ip.org

Can you help me please?

Thanks a lot for your attention

You’ve hit the rate limit due to using a shared DDNS domain.

Either switch to a DDNS provider on the public suffix list or get a “proper” domain (this can be a CNAME to your no-ip host).

Ok, thank you for your answer :slight_smile:
