Issues with Home Server VPN through L2TP/IPSec
Posted: Thu Sep 12, 2019 6:10 am
I am struggling to find proper logging in the event viewer regarding an ongoing issue with vpn connectivity. I am running a vpn through l2tp/ipsec on a windows server (2019) and am having a client connect via a windows 10 vpn connection. The client is immediately prompted a username/password when attempting to connect to the vpn, but afterwords the vpn says "connecting..." until the attempt fails. Meanwhile the vpn server is not receiving errors or connection attempts for the vpn in event viewer. What are some diagnostic steps for us to take to identify where the connection is failing?
