Synology DSM 6.2.4-25556 Update 2
My domain is: alphadata.si
I ran this command: under Control Panel -> Security - > Certificates - > add a new certificate - > Get a certificate from Let's encrypt
It produced this output: The Let's Encrypt server is busy. Please try again later.
Tested all the DSNs inserted under the "Subject alternative name" section against DNS A and /or CNAME records on my Provider's DNS server. All exist. The DSM version should also be the one, where the queries against Let's Encrypt servers work as I've red on different forums and other internet sources.
The IPv6 under Network section of ControlPannel is on " Off ", which could be the reason for some communication errors. Port 80 in forwarded on firewall/router to the Synology station.
What am I doing wrong?
My web server is: built-in DSM
The operating system my web server runs on is : Synology DSM (linux in reality)
My hosting provider, if applicable, is: No hosting provider
I can login to a root shell on my machine : yes, with putty usually from Windows
I'm using a control panel to manage my site: depends
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): Not my case.
I've upgraded to the DSN 6.2.4-25556 Update 6, which is the last version of the DSM 6th generation OS. The result is the same. Let me know that the upgrade to the v7.0 (and its successor v7.1 ) is recommended but not required. Synology still develops the 6th generation of DSM.
