Synology disk cannot reach LE server

[Dajlr]

My domain is:mystation.cz
I ran this command: Wizard to create new cert.
It produced this output: “Filed to connect Lets Encrypt. Please make sure …”
My web server is (include version): DSM 6.1.7-15284
The operating system my web server runs on is (include version): DSM 6.1.7-15284
My hosting provider, if applicable, is: UPC
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):YES

Hello can somebody help me with this ? I have redirect port 80 to local address of synology centrum. Is it necessary something else ? Can I resolve this problem deeper ? I cant find any logs… I red some topics here but without any help. (I turned off IPv6.)

Thx

Martin

Can you SSH in?

curl -vvv https://acme-v01.api.letsencrypt.org/directory
host acme-v01.api.letsencrypt.org
traceroute acme-v01.api.letsencrypt.org

@_az

host acme-staging-v02.api.letsencrypt.org

Curl with "HTTP OK" reply
host -- did you mean ping to host ? if yes - response ok
Traceroute without any responese

Would you be able to show the verbatim output of all 3 commands? The devil is in the details (usually).

Edit: actually, nevermind, I think the error message is just misleading and you cut off the important part:

“Failed to Connect to Let’s Encrypt. Please make sure the domain name is valid.”

Your domain doesn’t have any A/AAAA records, it doesn’t resolve.

What’s the full error message from the wizard now?

The same …
“Failed to Connect to Let’s Encrypt. Please make sure the domain name is valid.”
