I have a DS213 and I try to create a certificate with Let’s Encrypt but it is not working.
I have the error : “No response form the destination server.”
I tried both with my domain and my sub domain, same issue.
- Ports 80 and 443 are opened on NAS and router
- Domain is responding fine
- Web Station is installed and working fine, if I type the sub domain name I reach the page
- I opened SSH and did a “sudo cat messages | grep letsencrypt” which is giving me : “100 [Server is not reachable.]”, which is wrong as my domain is reachable.
What can be the issue ??
