I ran this command:./letsencrypt-auto
It produced this output:There were too many requests of a given type :: Error creating new cert :: Too many certificates already issued for exact set
Please see the logfiles in /var/log/letsencrypt for more details.
My operating system is (include version):ubuntu14.04
I assume you didn’t take a backup before re-installing the system ?
In this case, if you have no backups, and you have created new certificates 20 times, then deleted them and re-installed the system to try again … all you can do is wait I’m afraid.
If you are “testing” which it appears you are, then you can use the “staging” server to generate certificates and test your system - these certificates are not trusted by browsers, but can be used to test your process of generating a certificate.
