IIS Errror Firewall issue?

Here is the log, how can I get the SSL installed?

I’m using IIS and I do not know how to open the firewall to allow the Cert. I cannot post the log here

Hi, opening your firewall depends on how your server is hosted and it gets complicated if you are trying to host a server from home(?). You can also use tools like http://letsdebug.net/ to check your configuration.

Windows Firewall would be the first place to look but if you are hosting in a virtual machine (e.g. a cloud vm service) you will need to open port 80 and 443 tcp there as well.

If you are hosting a service at home then you need to forward port 80 and 443 to your server/machine form your router.

Really though I’d recommend chatting with someone local who knows about firewalls and ports etc as it can get complicated.

You can also look at using DNS validation (see the Authorization tab) instead of http validation as then you don’t need to have http ports open, but you do need to be using a supported DNS api or acme-dns. https://docs.certifytheweb.com/docs/dns-validation.html
