I have a problem with me will always display these errors page in few days
Error creating new cert :: too many certificates already issued for exact set of domains: static.244.115.9.5.clients.your-server.de.
Type: urn:acme:error:rateLimited.
You’ve been obtaining one certificate a day for this domain since May 20. They are good for three months. The most recent one will not expire until September 13.
So you don’t need to issue another certificate for this domain at this time and can safely wait out the rate limit.
However, you do need to fix your crontab so it stops requesting a certificate every day, so this problem doesn’t recur. You must have some sort of --force or similar option in there that is causing your client to renew certificates even though they are not expiring that should be removed. Please paste the cron entry that runs your Let’s Encrypt client if you’re not sure.
