I can access to the URL without problem but let’s encrypt keep returning me an error.
My domain is: vtt.enzomuhlinghaus.com
I ran this command: I tried to create a certificate for this domain that has Dynamic DNS linked to my NAS SYNOLOGY.
It produced this output: Failed to connect to Let’s Encrypt. Make sure the domain name is valid.
My web server is (include version): My NAS SYNOLOGY
My hosting provider, if applicable, is: Infomaniak
I can login to a root shell on my machine (yes or no, or I don’t know): no
