Hi, I have gone through the very same issue : bulb found on phone (both yeelight and mi home apps), trying to add it in the device list and connection timeout finally... It's been 3 weeks and 150 times (my estimation, not kidding !) I have tried to add the bulb in my network and device list and I finally succeeded today ! Here is what I did : turn on & off the bulb every second and sometimes even faster during maybe 1 minute. When I say "faster" I mean the bulb didn't even had the time to show up before I shut it down again... Just on/off like a crazy ! The bulb did reset several times but I kept shutting it down again and again quite fast. Ok, that looks desperate behavior, but hey... I launched Mi Home app again (connected to Main China server) and bulb connection worked immediately !!I'm now happy . All is working smoothly !Maybe you can try this if you are as desperate I was and confirm you get as lucky I am... I hope it can work for some of you and help you getting back to relaxing mood under the nice yeelight bulb light Cédric.
It seems the bulb is in factory mode, please have a try with:
