Taking just the first such error reported, here an annotated TCC log from that period.
The telescope was slewing. Suddenly the altitude status went bad and the altitude axis halted. This was not something commanded by the TCC, so you'll have to look elsewhere for an explanation. 1800 is the usual generic halt -- amp_bad and out_closed_loop.

(...gap...) the telescope finishes slewing and starts tracking. Alt is still bad.

An offset is requested. However, the axes are halted from the AXIS INIT, so it is rejected. (You *can* insist that an offset restart halted axes, but that was not done).
