Help with renewing certificate

Maybe a stupid question but when I try to renew, I get command not found:

$ letsencrypt renew --dry-run
-bash: letsencrypt: command not found

$ letsencrypt-auto renew
-bash: letsencrypt-auto: command not found

$ sudo letsencrypt-auto renew
sudo: letsencrypt-auto: command not found

What do I do wrong?

To run letsencrypt-auto, you need to use the following syntax:

./letsencrypt-auto renew --dry-run

You also have to run it from the directory to which you git clone'd letsencrypt. It’s not a system-wide binary (unless you installed it through your package manager).

tx! that helped but now we have a new problem:

An unexpected error occurred:
There were too many requests of a given type :: Error creating new cert :: Too many certificates already issued for:

I have a free dns provider…
I tried renewing only once and only for my mydomainname.
What can i do?

There’s no way to reset or bypass the rate limit of 5 certificates per domain per 7 days.

If you want to stick with a DynDNS provider, try one that’s included on the Public Suffix List. That way, you won’t share any rate limits with other users.

You could also get a free .tk domain at and create a CNAME record pointing to your existing DynDNS domain, and get a certificate for that. CloudFlare provides free DNS if needed.

Is there any hope for an solution for no-ip users to be expected soon? I mean, by now I’m not the only one that has to renew…
