Hi @navidz
if you have that error
your client is buggy. Check, if there is an update or switch to another ACME-client.
Reading your output
"During secondary validation: Fetching http://chwld.ir/.well-known/acme-challenge/62L18zcGjzQSCGa-N6N5e1u4u4tGek7qVkTHIinfvW4: Timeout during connect (likely firewall problem)
"During secondary validation" is the key.

So the primary Letsencrypt server is able to connect your domain, so your general domain configuration is ok.
But the secondary servers are blocked, so the secondary validation fails.
May be a regional firewall or something else. You have to find and open that instance.
