Hey all, I’ll start off by noting that I’m far from a networking expert, so I apologize if I’m not explaining the situation properly. I have a Synology DiskStation DS216j NAS device setup on my home network and I’ve setup DDNS config on my router as usg.alllday.biz via Google Domains. I usually access my NAS remotely via VPN configuration on my router, but whenever I want to allow temporary access for a friend I would like to simply forward the necessary port on my router to allow the friend to access the NAS via a secure connection. I had obtained a SSL certificate from Let’s Encrypt several months back, but I accidentally let it expire so I am trying to renew the certificate. I made several requests for the certificate yesterday while tinkering with my router configuration after each failed attempt, and there were a few times when I’d received a different error message than what’s shown below, but now my requests are being denied and I believe it’s because I made too many requests (none successful, as far as I’m aware).
I have confirmed that my NAS is setup for external access and that my router is configured to allow connections, and I’ve successfully tested this from outside my LAN. Any help would be greatly appreciated!
My domain is: usg.alllday.biz
I ran this command: N/A. I’m not familiar with the specific commands; I am requesting the certificate via the control panel of my Synology DS216j (DSM Version 6.1.7-15284).
It produced this output: Failed to connect to Let’s Encrypt. Please make sure the domain name is valid.
My web server is (include version): Don’t know
The operating system my web server runs on is (include version): Don’t know
My hosting provider, if applicable, is: Verizon FiOS
I can login to a root shell on my machine (yes or no, or I don’t know): I’m sure I can since I am the network owner, but I’m not familiar with this process.
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): Yes. Synology DiskStation device, model DS216j. Control panel is built in to the DiskStation Manager Version 6.1.7-15284.
