Good evening all, is it possible to use letsencrypt inside a small company (domain) for a intranet Site? The site is not availible from Internet just in company domain. Thanks in advance and best regards

Yes, it possible. Probably, since you do not want to allow inbound HTTP access to your web server sitting on your intranet, you must fulfill DNS-01 challenge instead of HTTP-01 for that domain name.

On that Windows 2019 machine, are you able to successfully open https://acme-v02.api.letsencrypt.org in a browser?

That's pretty weird! Sounds like something is wrong with the Trusted Roots on that server. They usually get updated via Windows Update, is this server fully patched? You might be able to manually download the "TrustID X3" root from https://www.identrust.com/support/downloads and install it to you…

Are you in a country, or on an ISP, that is banning access to LE? Do your DNS servers resolve other sites?

Hello, the server is or was full patched and there is no more updates availible. I will try tomorrow with manually downloading "TrusID X3" and let you know. @rg305 I dont think so because nslookup show me an intern address and with tracert i got 13 hops and from the 13 are the 1 Hop and 5-11 Ho…

You could do a very basic connectivity tests with: telnet acme-v02.api.letsencrypt.org 80 telnet acme-v02.api.letsencrypt.org 443 If they are successful, then it is most likely the trust issue.
