I am getting this error while trying to align with the Sun. I read your forum article on this, with the 3 possible causes. I know I have selected the Sun, and so it must be cause (2) or (3). I am using a Celestron NexStar Evolution, so Celestron WiFi. So SkySafari should be sending the correct time to the scope. So it must be (2), initial alignment model is very inaccurate.
So, is there a way to clear out the alignment model in the scope?
