Certificat for Synology server

[macgyver]

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: jeanlyon.fr

I ran this command:

It produced this output:

Cannot connect do Lets Encrypt
The operating system my web server runs on is (include version): ?

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
Synology Using DSM 6.2.2
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):

Hi @macgyver

@macgyver

My domain is: jeanlyon.fr

I ran this command:

It produced this output:

Cannot connect do Lets Encrypt

do you have a screenshot of that error?

Checking your domain there is a curious thing, may be critical - https://check-your-website.server-daten.de/?q=jeanlyon.fr#url-checks

Your http + https:

Server: Apache

But http + /.well-known/acme-challenge/random-filename:

Server: nginx/1.10.3

And your ip address:

Host	T	IP-Address	is auth.	∑ Queries	∑ Timeout
jeanlyon.fr	A	217.160.0.94 Neubrandenburg/Mecklenburg-Vorpommern/Germany (DE) - SCHLUND Hostname: 217-160-0-94.elastic-ssl.ui-r.com	yes	1	0
	AAAA		yes
www.jeanlyon.fr	A	217.160.0.94 Neubrandenburg/Mecklenburg-Vorpommern/Germany (DE) - SCHLUND Hostname: 217-160-0-94.elastic-ssl.ui-r.com	yes	1	0
	AAAA		yes

Looks like a server in a data center. So there is an Apache, but the hoster blocks /.well-known/acme-challenge.

Not your home server with the Synology.DSM.

You are absolutely correct I own jeanlyon.fr and I am starting a web site hosted by Ionos (former 1&1)
I am also running a Synology NAS (918+) home server hosting ‘music, videos and photos’ which I want to make accessible on the internet to selected friends and family.

Everything works fine using Synology ‘Quickconnect’ feature (http://QuickConnect.to/leperchay/photo). I also have a fixed IP address.92.xxx.xxx.xxx

Should I use a different method??

I read everywhere I should be using https to secure this access on the internet. To use https (just a tick on NAS preferences), I am advised not to trust the default Synology certificate and replace it with a Lets Encrypt certificate.

How to get such a certificate and make this work as expected??

How should I fill below screen?

Thank you for your help.
