Cannot connect any of the 4 color bulb 2s I purchased. Attempted to log in to update firmware with all of the accounts I could find posted here, including the dingyichen@yeelink.net account posted 9 hours ago but still no luck. Changed server DNS, tried different Android device, etc.
Any other workarounds I can try before they go in the bin?
I have the same issue but my bulb is actually not new, it worked perfectly for months and now suddenly it stopped and I keep getting connection timed out error when I try to reconnect to it. I tried all solutions except DNS change because my internet provider doesn’t allow that, I logged in with that account but same issue each time without any success, I would really appreciate a solution as well.
Same issue here. I have 6 or 7 Yeelights (Meteorite and Smart Square) which run for > 1 year on my 2.4 and 5 GHz network. No changes in passwords or other settings. One of the lights lost connection. I tried to reset ~10 times today, while changing various settings in between (e.g. DNS over HTTPs / TLS on/off, WPA2/3, 2 different Android phones).
No success. The app on my phone connects to the lamp, then it flashes briefly, stating “Updating connection status, just a sec…”. Then it times out. Please advise. This should not happen.
Hi there. The only thing that eventually helped me was to disable the password on the router.
I hope we can agree that turning off encryption on a private network is not a solution…
Same symptoms as Wolfsbein.
I can reset all of my Yee1 and Yee2 bulbs successfully.
However, after a power cut, my “strip plus” now always times-out.
It originally connected first time no problem.
One thing that I do notice is that the little blue led at the end of the strip controller goes from blinking to solid at about 75%, about where it would normally connect OK.
Hard to believe that this long-running problem remains unresolved.
UPDATE!!
After accidently leaving the app at “100% timed out” state for about an hour, I selected “Try again” and it connected immediately! 
UPDATE2
Fixed properly now. In my case the power cut caused an IP conflict when the router restarted.
When my strip added in the app it got a conflicting IP.
Now after a router reset the IPs are correct.
Tried to contact the support via the provided email support@yeelight.com today. Let’s see. Here’s what I asked for:
Dear Yeelight Support Team,
I am one of the many customers who have issues with connecting Yeelights to WiFi. Your own forum is full of such reports. I received my 2 Yeelight YLXD10YL Smart Square LED Ceiling Light somewhere in January / February this year. One of them somehow lost connection and is unable to reconnect.
I hope and honestly expect that you
Please let me know when I can connect this expensive light again and do not have to sit in a bright white light all evening long. If you cannot do that, may I ask you for an additional Bluetooth remote, so I can at least control it manually.
All the best,
Yeah, obviously. I use a second router as a wifi extender, and I temporarily turned ott the encryption on the main router, then it managed to connect to my extender (same thing it was using for half a year without a problem) and then I put back the password on the main router and it managed to keep the connection.
I also contacted them and never received any answer…
I found a fix for me!
My timeouts were caused by an IP conflict that happened when my router restarted after a power cut.
Resetting the router solved it.
Damm even I am having a similar kind of issue, I have searched all over the internet and even have posted on number of threads on different forum, no solution seems to work. I am really frustrated, can anyone of you here help me resolve this issue, I am very much tired now.
Same here… any help ?
If anyone is still having this issue, turning off wpa3 and leaving only wpa2 on my router worked for me.
