Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: wwolfden.cppexpert.net
I ran this command: Pressed a button in Synology DSM (Get a Certificate from Let’s Encrypt)
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): nginx/1.16.1, but it is Synology, so who knows
The operating system my web server runs on is (include version): DSM 6…2.3-25426 Update 2
My hosting provider, if applicable, is: me? (Verizon FIOS for connection)
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): no per se, but DSM is kind of a control panel
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot): nothing starting with cert on the path. find from root down finds nothing starting with certbot.
