I received the following email from Let’s Encrypt :
**Your Let’s Encrypt client used ACME TLS-SNI-01 domain validation to issue a **
certificate in the past 60 days.
**TLS-SNI-01 validation is reaching end-of-life and will stop working on **
February 13th, 2019.
**You need to update your ACME client to use an alternative validation method **
**(HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate **
renewals will break and existing certificates will start to expire
Since i am creating Let’s encrypt certificats through my NAS (Synology), I wonder if i have an action to do on my side or if Synology is taking care of this. I just intended to renew my certificates before date of expiration.
Thanks in advance for your answer.
