Not sure if this is related but the only thing I can find in those logs that seem to indicate what the problem may be is
[2020-03-25T20:24:24.090 PDT INFO ][ org.kde.kstars.indi] - iOptron CEM40 : "[WARNING] Please unpark the mount before issuing any motion/sync commands. "
So make sure to go to the Mount tab and click Unpark before you do anything else. Note that by default Ekos instructs the mount to park after polar alignment. You can disable that behavior by going to the Align tab and clicking the Options button to the lower right of the tab. The auto-park behavior can then be disabled in the Astrometry.net tab of the options popup.
