Hi guys ! I got problem when I tried to renew my certificate of my domain [ddigital.fr](http://ddigital.fr) on my Apache webserver I got this message > Attempting to renew cert from /etc/letsencrypt/renewal/ddigital.fr.conf produced an unexpected error: urn:acme:error:rateLimited :: There were too many requests of a given type :: Error creating new cert :: too many certificates already issued for exact set of domains: [ddigital.fr](http://ddigital.fr). Skipping. And when I checked [crt.sh | ddigital.fr](https://crt.sh/?q=ddigital.fr), I can see that certbot try to renew so many times my certificate... I had crontab until end of July but I removed it when I learnt that certbot do it itself. But, I still seeing soo many try and my certificate is invalid since end of July... What can I do ? Thanks for any help ! ---

How were you configuring the crontab? It sounds like you were configuring it to always issue a new certificate. You will probably need to look at the /etc/letsencrypt directory to find the a new certificate and use it, or wait until the rate limit expires to request a new one. ---

Hi ! Thanks for your answer ! My crontab command was `1 * * * 1 /usr/bin/certbot renew >> /home/dylan/certbot.log` So it was supposed to be launched every Monday but anyway if a certificate doesn’t need to be renewed it will be skipped isn’t ? I check my directory and I found an old file like ddigital-0001.conf that was not used, even if don’t see it when I try to renew certificates. So I removed it Is it certbot which try to renew my certificate every day ? How can I reinstall valid certificate ? (without wait until reset of rates) Thank you ! ---

> [@dylanschreier](#): > > 1 \* \* \* 1 /usr/bin/certbot renew \>\> /home/dylan/certbot.log This means "Every hour, at one minute past the hour, on Mondays". That might not be exactly what you meant. Maybe you were thinking of "0 1 \* \* 1" instead? Anyway, this is unlikely to be the root cause of the problem. But I'm not sure what you meant by "Certbot does it itself" — normally Certbot does it by having a `crontab` entry to run `certbot renew`, kind of like this one! On some operating systems the operating system package might use a `systemd` timer instead of `crontab`, but this is rather OS-specific. Normally `certbot renew` should only try to renew certificates that are near expiry, so running it frequently should not cause the problem that you saw. Can you perhaps post the results of `certbot certificates` (to see which certificates you have managed by Certbot -- this will have changed as a result of your deleting the `ddigital-0001.conf`, though) and `ls -l /var/log/letsencrypt` (to see how often Certbot is currently being run) ---
