As others before me I can't get an LE cert on my NAS.
My DDNS provider is noip.com, I have done the following after reading other posts of similar problems:
ports 80 and 443 are open, I've tried it with both Webstation running and without, I've made sure that my ISP only issues IPv4.
Multiple attempts without the command coming back with too many attempts (so most likely not connecting at all). Current installed cert is synology standard.
My domain is: laundrynas.ddns.net
I ran this command: Built-in synology function
It produced this output: Can't connect to Let's Encrypt, make sure domain is valid
The operating system my web server runs on is (include version): DSM 6.2 (Linux)
I can login to a root shell on my machine (yes or no, or I don't know): yes
all help much appreciated!!
