Accessory Not Found - HomeKit

I recently tried to re calibrate all my yeelight bulb 2 since there was a lag in communication. I reset all my bulbs, deleted HomeKit and removed all bulbs from the yeelight app. I reinstalled in the yeelight app but when I try to add to HomeKit I get a error, “Accessory not found” . My wifi is all on 2.4ghz, same name and password and there is a clear signal throughout the house.
Please help !
