Why is my camera not connecting?

My wifi camera suddenly disconnected from my phone, I tried rebooting it and tried connecting it directly to an ethernet cable and still no sign of it, tried to reset its settings by using the reset button and still have no result whatsoever.

My camera is EasyN, sorry for choosing the wrong device but I couldn’t find it in the list.

Ps I went to several local repair shops and none of them even tried to fix it, so you’d be helping me big time.

Thanks !
