Bluetooth device connection problems

We have built a HID/MIDI multifunction device and are having connection problems only on Windows (works on iOS, Mac, Android). It only happens on some Windows PCs. I think it happening because Windows rejects several connection parameter requests and then terminates the connection, but I don't know why it is doing that. I've attached a packet capture from BTVS. You can see in frame 297 a connection parameter update request is rejected, and then in frame 299 the host sends a disconnect. Could you confirm this is what is happening, help me understand why Windows is terminating the connection, and what we can do about it?

Thanks
