Acme_do_auth failed

I have a windows server that is running Surgemail and i have opened ports (80, 443) and i continue to get the challenge error. I do block countries and only allow the US as this is a personal mail server. I would like to see if anyone can help with this issue.
Thanks in advance.

My domain is:

I ran this command: tellmail ssl_update

It produced this output: Challenge: error: Fetching Timeout during connect (likely firewall problem)
acme_do_auth failed
Update finished, 0 good, 1 bad

My web server is (include version): Surgemail Version 7.7i-1, Platform Windows

The operating system my web server runs on is (include version): Windows Server 2016 Standard

My hosting provider, if applicable, is: SmartCom Internet

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Surgemail

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): Surgemail

Geoblocking is unlikely to be compatible with Let’s Encrypt’s validation system. As a first step, it would be best to either turn that off, or use the DNS-01 method for validation.


i will give that a try.

You could also try Geo/WhatEverYouWant blocking HTTPS [but not HTTP].
And [forcibly] redirect all HTTP to HTTPS [except for the LE certificate challenge requests].
