Action is required to prevent your Let’s Encrypt certificate renewals from breaking.
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.My domain is: https://a1a-studios.synology.me
I ran this command: none
It produced this output: none
My web server is (include version):synology NAS server
The operating system my web server runs on is (include version): DSM Version: 6.2.1-23824-4
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel)
IM CONFUSED ABOUT THIS EMAIL, SHOULD I UPDATE THIS? IS THIS A GENERAL EMAIL?
I got the same warning email today. Running same DSM version on a 1815+.
No information in the email showing the domain, and it only says its in the last 60 days, so no help there either. My cert is valid, but will it be after Feb? Is there a way (command line or otherwise) to check what method was used?
I got the same warning email today. Running DSM 6.2.1-23824 Update 4 on a DS418play.
The email also doesnt show the domain. My cert is also valid and I updated it today (no problems), but what will be after Feb?
I have no Idea how to change the Method on the Synology Diskstation. Do you have any suggestions? How can I check the method which is actually used?
Thank you [JuergenAuer] as far I can remember the certificate was going to renew in automatic mode. Synology was very kind in helping me with the install it on WordPress. it has been working great and e-commerce settings are all in the green but is only for one website. I contacted them for any documentation they might have on this issue but if you say they don’t use this, is cool too.
