I have setup the server and can access using a Android Phone, Windows 10 Pro and older Ipad (did not right down the version of iOS) but on a IPAD that is fully updated the VPN will not connect. I get the following error "The L2TP-VPN server did not respond, Try reconnection."

Here is the log on the server I get from the IPAD connection
