Failed to perform handshake and fetching data errors

Running the latest version available in HACS v0.8.2

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.
