I am trying to get Routing and Remote Access Server to work and had put in a lot of time to find out why I can't establish a successful connection for a machine tethered from my iphone. I have setup an assimilation network using Essential 2016 and my other desktops/laptops to connect to it but I am pretty much stuck.
The Essential server is set up with RRA service and I used the Dashboard to install the service. I used this guide to install just the RRA service and not IIS:
port 443 is opened on router
I am getting this error ID 22 from event log on the server: The SSTP service could not be configured to access incoming connections. The detailed message is provided below. Correct the problem restart the SSTP service. Access is denied.
I check AD and grant each account to access incoming RRA connection.
I have tested the vpn connection (tethered to LTE wireless network) and it looks like it is trying to verify the username but it throw out an error:
Error 800: The remote connection was not made because the attempted VPN tunnels failed. The VPN server might be unreachable. If this connection is attempting to ue an L2TP/IPsec tunnel, the security parameters required for IPsec negotiation might not be configured properly.
Please help.
