Bonjour,
Depuis la réactivation de mon domaine sur mon NAS synology je rencontre des problèmes de génération de certificat SSL avec lets encrypt.
En effet, l’interface de mon NAS me retourne une erreur de type :
Après vérification sur le site “https://transparencyreport.google.com/https/certificates”, je vois 3 certificats actifs sur mon domaine et mon sous domaine :
Comment puis-je résoudre le problème ?
Merci de votre aide 
Hi @jemy
there is a hidden check of your domain - https://check-your-website.server-daten.de/
You have created a new Letsencrypt certificate:
2020-03-26 11:25:39
So use it.
Your website has a timeout. But there are correct _acme-challenge TXT entries. Looks like dns validation has worked.
Hi @JuergenAuer,
Thanks for your response.
In fact, i have create certificate manualy with sslforfree and import this certificate with synology interface.
This is not tha i want beacause if i configure certificate with the synology interface, the certificate reneweal is make automaticly.
Can i revoke all certificate ?
If you want to wait one week ...
The main limit is Certificates per Registered Domain (50 per week)
I don't understand why i have an error. I have only 3 certificates on the same domain.
