New encryption from firmware 1.21

[nygma2004]

First of all, thanks for this node.
I am using this to control 2 different split units without any issues. But there is a bigger unit which looks more like a commercial unit mounted in the middle of the false ceiling.
When I enter the IP of it's wifi module, it is not able to connect.

I see the following in the debug log.

SOCKET Unable to connect. Retrying...
>>> cid:9424b827fd75: 6/29/2024, 10:55:13 AM
SOCKET.SEND { t: 'scan' }

Any recommendation how to get this working?
