Xiaomi Yeelight Smart LED Strip - Connection Error

Hello, I’m trying to set up my ledstrip with the yeelight app (the strip was disconnected by itself for no reason and was appearing offline no matter what), but i either get an error at 50% of the sync process or at 100% where it says that connection was interrupted. Every other wifi device I use works fine, connection is also fine. I can’t figure out what the problem is.

Please reply soon,
thank you for your time,
