Although a screenshot of half a page of the log is not much to go on, and I have no idea whether this is related to your problem, I do notice that you have put in some values for “Solver Extra Args” in the ansvr settings page.
-r this is the same as using the checkbox “sort stars…”, why not just use the checkbox?
--objs 1000 this is the same as the “Objects:” setting, so why not use that?
-H 2.5 -L 1.50 these are the most problematic. SGP will rescale images before submitting them to the solver, and if the rescaling done by SGP results in a scale that falls outside these bounds your solves will likely fail. I would strongly advise removing those from “Solver extra args”.
The other thing that is suggested from the screenshot is apparently no image was submitted to ansvr for solving. Is SGP configured to use ansvr? I could be wrong about this because we cannot see the whole log file. If you want to post the full log file it can be found on your machine at:
