Dns error on windows server for my subdomain

A few months ago, I had ubuntu on my vps and got LetsEncrypt ssl easily for running BBB on my subdomain (live.sadatsch.ir).
Since I had to do some changes to my dedicated server, I deleted ubuntu and installed Windows Server 2019 (Build 17763) instead. I installed IIS and ran ftp service for live.sadatsch.ir, but when I try to set Letsencrypt ssl by win-acme.exe, I face an error that relates to dns (attached picture).

My domain is:
I ran this file:
last version of .exe file win-acme.v2.1.15.1008.x64.pluggable
It produced this output:
Target generated using plugin IIS: live.sadatsch.ir

[live.sadatch.ir] Authorizing...
[live.sadatch.ir] Authorizing using http-01 validation (SelfHosting)
[live.sadatch.ir] Authorization result: invalid
[live.sadatch.ir] {
"type": "urn:ietf:params:acme:error:dns",
"detail": "DNS problem: NXDOMAIN looking up A for live.sadatch.ir - check that a DNS record exists for this domain",
"status": 400

My web server is:
The operating system my web server runs on is:
windows server 2019 - Build 17763
My hosting provider, if applicable, is:
A VPS on my dedicated server.
I can login to a root shell on my machine:

Ok. It is a little mistake when I was typing the problem, and It is true in my server as you see in the picture.

The domain in your picture doesn't exist…

everything was ok for ssl on linux ubuntu on my subdomain live.sadatsch.ir
But it shows that error on windows server!

Again, you're trying to get the certificate for domain live.sadatch.ir (note the missing s between t and c), this domain doesn't exist. Domain live.sadatsch.ir (with an s) does exist.


That's right. just an error in typing the domain !!!
So many thanks for the help.
