Failed to perform handshake and fetching data errors

Configuration

Config done via UI

Describe the bug

I have two Cooper and Hunter ACs that are connected via the USB plug. I have connected them to my Midea Air app and can control both units without issues. When I go through the UI setup for the configuration, it does not find any devices. Only when I specify the IP for one of the ACs, then the integration finds both ACs. However, while both ACs are correctly found and added, as soon as I try to control them, they become unavailable.

@poldim can you check if problem persists in version 0.8.10?

@poldim can you check if problem persists in version 0.8.10?

Hey, just tried to see if this works this weekend and it appeared to bring in my two mini-splits on v8.12.

Unfortunately, looking at the devices from the past day it does not appear to be communicating reliably. Are you aware if anything can be done to improve the stability of these devices? In parallel, I will do some checking to make sure it's not falling off of my WiFi network this week.

The mini split was roaming to an AP two floors away. I've locked it to the local AP and this solved the AP going unavailable.
