Xiaomi lamp 1s Failure to update and failure connection with Homekit

Hello, I bought this Xiaomi lamp 1s from China and is using it in the UK. I found it difficult to connect to my HomeKit, and even if it succeed for some time, it will disconnect within a day automatically.
When I try to upgrade lamp, I always have a failure notice from Mi app. Could anyone please help?
