Connection timeout

I’ve been trying for two days. Changed everything. But still not working. Reset after reset, change server, dns, and stuff, yet still. Urgh help!

Hi,
Are you using 2.4GHz WiFi?

Yes. 2.4ghz

Please try to use one phone as router to share a hotspot, use another phone to connect it.

The same issue with my bulb, how we can solve this?
