I ran this command:
certbot-auto
It produced this output:
An unexpected error occurred:
There were too many requests of a given type :: Error creating new order :: too many certificates already issued for: stratoserver.net: see https://letsencrypt.org/docs/rate-limits/
My web server is (include version):

The operating system my web server runs on is (include version):
ubuntu 18.04 TLS

Hi @wimedko

you shouldn't use that domain name. stratoserver.net isn't on the Public Suffix List, so the domain name is a subdomain.

There is a limit of max. 50 certificates per domain. So it's nearly impossible to create a certificate with that domain name.

Isn't there an own domain name you can use?
