Yeelight firmware

Hello to everyone. I cannot upgrade the firmware in 3 ceiling lamps. I’ ve tried every solution i’ve found.

Resetting, tried all servers.

My network is 2.4 and yes ive changed dns servers.
I’ m getting timeout error both on yeelight app and mi home app.

Any help is welcomed, thank you.
