Hello
I use an AWS EC2 machine UBUNTU 20.04 and I recently got an email reminding me that my Let's Encrypt certificates (for my rstudio-server and shiny-server) were expiring in 13 days. So I try to renew them with the command : certbot renew --cert-name mydomaine-name --nginx or sudo certbot renew --dry-run
And I get as error :
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Renewing an existing certificate for mydomaine-name
Failed to renew certificate mydomaine-name with error: urn:ietf:params:acme:error:rateLimited :: There were too many requests of a given type :: Error creating new order :: too many failed authorizations recently: see Rate Limits - Let's Encrypt
All renewals failed. The following certificates could not be renewed:
/etc/letsencrypt/live/mydomaine-name/fullchain.pem (failure)
1 renew failure(s), 0 parse failure(s)

The too many failed authorizations recently error would only present itself if renewing failed for a different reason before. Please check the logs and preset the log file where the actual error for renewing revealed itself.
Also note that this error is from a limit of 5 failures per account, per hostname, per hour. This would not happen if a regular renewal attempt would fail, as it's customary to try to renew twice a day, which cannot hit the aformentioned rate limit.
Also, if you look closely, the --dry-run should give a different (and in this context more useful) error because it will use the staging server instead of the production server. You're unlikely to have hit the rate limit on the staging server, so you'll probably get an error that corresponds to the underlying reason that the previous attempts failed.
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
Failed to renew certificate mydomaine-name1 with error: Some challenges have failed.
