Robovac l70 hybrid doesnt connect to the app

I was using this product without a problem for a month. Today while it was cleaning i checked my eufyhome app and the device was offline. I waited until it finishes and go back to the dock but it was still offline. Then i deleted the device from the app to reinstall it but hell no… After trying everything for 3 long hours nothing worked. Yes im using 2.4 and yes mobile internet is off… First it couldn’t find my device at all then after %99 connection failed message appeared. Also in my modem settings i can see my device is actually connected to the wifi (and wifi signal is solid blue on the device) . So i think the problem is the app here. Can anyone help?
