Yeelight w3 - Can't set up - connection timed out

Hi, trying to set up two bulbs for 2 hours now, cannot get them working. Have set WiFi network to 2.4ghz only, have tried connecting to China servers, can’t change dns due to isp router though, have tried in different places.
Have tried setting up with Xiaomi home, still same thing, fails to connect bulb to network

Anyone know how to fix this?

I think W3 are only for overseas markets and will not work on China server, did you try other servers?

Yep tried every server available - still the same thing
