I have been very happy with my Yeelight products until now. I use the Mi Desk Lamp, Light strip and RGBW bulb. Everything worked well for months, installation was flawless and Google Assistant worked perfectly with Singapore server.
Now today, I tried turning on my usual scene in the Yeelight app, and it doesn't work. It shows the lamps as offline. I check if they maybe lost connection, but all 3 lamps show up in my router.
Next, I delete the app data, reinstall it and log in. Still offline.
I remove every device, reset every single lamp and try to set it up again, but it seems that it can't reach the servers. I suspect this because my phone finds all 3 lamps when reset, the WiFi scan is sucessful, the phone shortly connects to the lamp to push the data, and then nothing happens. The lamp is connected to WiFi, I see it in router interface, but can't talk to the server I suppose?
Any idea? Maybe a Yeelight server IP address I could try to ping from my computer to see if it's my router that can't reach it?
I'm pretty much clueless.
Other than that, I really have to thank you for the amazing products you have put out there. I am very sad not to be able to use them right now.
