I am getting an error in the Certify SSL Manager when I am testing the certificate setup:
Could not verify URL is accessible: http://remote.domainname.ca/.well-known/acme-challenge/configcheck
I installed the Certify SSL manager on the Essential server 2016 and following the steps to setup a free certificate for vpn service.
Do you know why?
Is port 80 open? Do you have a Host A record pointing to the public IP address of your server?
How are you doing Helen?
I swear the port 80 is open as well 443 but when I run the repair wizard on the Anywhere Access, it keep saying to open port 80, so I don't know what's going on.
Do i create the A record on the essential server? When I was using the free Microsoft SSL for Anywhere Access, I did not get that error and so I know port 80 is open.
The Access Anywhere wizard creates a zone for remote.domain.com and that zone has an empty Host A record with the IP address of the server. This will take care of local name resolution of the domain remote.domain.com.
In public DNS we will also need to make sure that remote.domain.com resolves to the Public IP address of the Internet connection your server has. If your Internet connection has IP address 220.127.116.11 we need to create a Host A record for remote in the zone domain.com that has 18.104.22.168 as the IP address. Clients from outside your Lan will resolve remote.domain.com to 22.214.171.124 and to whatever service you have running. That can be Access Anywhere web portal at https://remote.domain.com/remote or your VPN connection.
The above method is called split-brain DNS. The certificate you need must have remote.domain.com on it
