Timeout in requesting a new certificate

My domain is: http://crm.granotec.com.br

I ran this command:

Let’s Encrypt Windows Simple (LEWS)
N: Create new certificate
1: Single binding of an IIS site
Choose site: crm.granotec.com.br (SiteId 2) [@C:\inetpub\wwwroot\crm]

It produced this output:
[INFO] Answer should now be browsable at http://crm.granotec.com.br/.well-known
[EROR] Authorization result: invalid
[EROR] ACME server reported:
[EROR] [type] urn:acme:error:connection
[EROR] [detail] Fetching http://crm.granotec.com.br/.well-known/acme-challenge/
9W-6SQgb8N5otUDiauKM-vruTpoROeTFyD3nmka9cEA: Timeout
[EROR] [status] 400
[EROR] Create certificate failed

My web server is (include version): IIS 8.5

The operating system my web server runs on is (include version): Windows Server 2012 R2

My hosting provider, if applicable, is:

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): no

Looks like your site isn’t responding to http requests. You’ll need to fix that before you can obtain a cert this way.

I made tests with requests to it and it’s normal, i can’t figure out what is… btw, the configtest works! http://crm.granotec.com.br/.well-known/acme-challenge/configcheck :sweat:

You may be able to connect to it, but Let’s Encrypt, danb35 and I can’t.

Can you connect to it from other networks? Other countries?

According to portqry, none of your ports are open to public. (Which means you probably use an internal network)

Thank you
