My domain is in blacklist


I’ve been running a web application called “https://jp.知名度.net/ (https://jp.知名度.net/)” and “” in Heroku for 3 years now, and since April 12th, I’ve been getting “Let’s Encrypt domain blacklist” error in Heroku’s automatic certificate management.
How can this be resolved?

(I made this post because I read this: Domain blacklist)

Hi @inamori

see that topic, yesterday:

There is no “blacklisted” from Letsencrypt. That user has created a certificate 2020-04-13.

Ask Heroku what that means. Or check, if there is a better log.

Checking your domain - - you don’t have a new certificate.
