Well, nope, never had something specifically a communications error.
I've seen a lot of things that were indescribably odd. And things that would break the will of strong men and make them walk away from Astrophotography.
But when such carp swims by, I have often just shut down, and started over. (The big reset) Go back to boot up.
Or shut down, then come back the next night when the square electron has gone away.
Glitches occur. Seems to be the nature of the sport. Millions of backyard astronomers, using billions of combinations of settings and all sorts of combinations of equipment.
Nope, there are no cut and dried solutions.
Dispite what the software writers may have you believe.
But when everything works fine, OH! What a feeling!
