Yeelight bulb color can not be dedected

I live in Thailand, my server is Singapore, I am trying to detect the Yeelight with my Google Home app and with the Yeelight app, I reset to factory settings many times, but all in vain.
What to do?

1、You need connect the bulb to Yeelight application firstly;
2、From google home application, link Yeelight to google smart home. You will see the bulb if link successfully.

You mean: go to google home>add device>set up device>works with google> select the app yeelight.> sign in> in the yeelight app add device> elect led bulb color> turn the bulb on> install device>next>scanning device?? It is not working, it just does not find the bulb, and I have 2 of them!!

1、Which platform of Yeelight application do you use, Android or Ios?
2、What’s version of the application? Is it the latest?

Same issue here… 2 bulbs cannot found during scan.

Android + last version for both mi home/yeelight app.
