Can't connect Android device as a Hamachi mobile client

Hi everyone, I am trying to connect an Android device as a Hamachi mobile client by following the instructions here:

https://documentation.logmein.com/webhelp/EN/CentralUserGuide/LogMeIn/t_hamachi_MobileClient_Android.html

Unfortunately, it doesn't work. I have installed the 3 certificates, and configured the VPN as described in the "Preview Android config" section of the Mobile tab in the Edit Client page (I tried IPSec Xauth RSA, with a number of different combinations of certificates)

When I try to connect to the VPN in Android, it just pauses for a few seconds, and then says Unsuccessful. I've tried two different Android devices, one on 8.1.0 and one on 7.0, neither works.

Any help appreciated.
