We have set up the VPN on this router without changing the DNS Provider. And I was able to connect to this VPN from my windows 10 PC the first day. But later when I tried to connect again, I got an error on my PC that says "The connection was terminated by the remote computer before it could be completed". The windows event log had this messge "The link to the Remote Access Server has been established by user xxx". However, I was able connect from an Android phone. I am new to VPN and would greatly appreciate any help.
