Session deleted due to admin initiated termination on APM 13.1.0.2

I have a number of users connecting to our VPN, and when we moved them from 12.1.2-HF2 to 13.1.0.2 last night, they started getting disconnected every 1-2 minutes. It doesn't just try to reconnect, it kicks them back out to the login page.

Server logs show the following:

Feb 9 08:27:40 tmm[18611]: 01490520:5: /Common/access_policy:Common:85ebb6d9: Session deleted due to admin initiated termination.

The only thing I can see in edge client logs is this:

4500,4736,Standalone, 48, , 1248, CStandaloneDoc::OnDisconnected, A network error has happened (Session state: 2 Fav state: 3). Trying to reconnect VPN

I did see these logs too:

Has anyone else seen this issue? It sounds like something isn't getting installed properly and by the time the F5 looks for it the user gets disconnected.
