Win L2TP with Cisco ASA

So we migrated to a new firewall ASA 5516-X. Previously we were using Windows L2TP remote access VPN but since changing to the ASA we are having issues using it.

Some people can connect, some cannot. Some people can connect from one ISP and then not from another. It doesn't make any sense to me. I have engaged TAC and they are telling me the ASA is configured correctly and it is not the cause. I am getting a lot of grief since it stopped working afer firewall migration. The error we get is 789. Google tells me some things to check but that is for issues connecting full stop not for intermittent connection issues.

Anyone got any pointer for me to look into? I will be very grateful.
