HabDroid Beta ssl-handshake-failed

I am running Openhabian, thus openhab 2.x and the android app beta.

I found other posts about this but, they are pretty old…

I have the android app beta on my android pone and it works fine. No issues when I’m on my home net or via VPN on my home net.

But I added the beta app to an android tablet and I get the ssl handshake failed message.

Most of the other post seem to be solved by changing the cipher setting.
But, since it works fine on the phone and not on the tablet I hesitate to change the settings…actually, I haven’t figured out where the other posts actually make the change…

Update: It also works on another android phone and another android tablet…
