Let's Encrypt Certificate Renewal on Synology NAS

Synology NAS DS916+


I have reinstall my DS916 with 2 SSD drive’s. So I have to start from scratch. OK NO problem. I import my Let’s Encrypt Certificate form 4 months ago. Now I get the message expired what I understand.

Can I re-issue or revoke my certificate URL?
Port 80 and 443 is open…

Thx Rob72

Hi @Rob72,

Let’s Encrypt certificates are only valid for 3 months. Since it’s more than 3 months since your certificate was issued, you should get a new certificate by following the same procedure that you used to get the first one.

Thxs for this information, greet. I follow your advice.



Thx You solve my problem, it was working directly, Greet Thx Rob72
