Too many certificates already issued for:


I have tried to use the Certbot ACME client with my url to get a certificate. But I get the following error: "Too many certificates already issued for:"
But I can find “” in the Public-Suffix-List.

What can I do to get a certificate for my url

Best regards

I ran this command:
sudo apt-get install python-certbot-apache -t jessie-backports
certbot --apache

It produced this output:

Hello @eneo99, was added to Public Suffix List just 8 days ago so you should wait a few weeks till the change is deployed into Let’s Encrypt boulder.

Edit: In this post Public Suffix List update schedule? you could have more info about this process.

Maybe @cpu could be kind enough to perform a pull to accelerate the inclusion of these new domains. :wink:



Hi @eneo99, @sahsanu

I’ll be updating our publicsuffix-go dependency shortly to support IDN top level domains ( ). This should also include's addition to the PSL and resolve @eneo99’s rate limiting problem.
