What is error code -1008?

I am getting every time I try to take off. Because of the error, I can not launch. This is with a DJI Air 2S. The DJI Fly Now app works fine with no errors.

Finally figured out the problem. I live in a restricted area due to a nearby airport. I had to first unlock the restriction with DJI Fly then switch back to Litchi. Now I can take off and fly using Litchi.
