Section in here about shoestring astronomy and GPhoto use with DSLR;
"When using external shutter release cable, you must use the GPhoto generic driver and not a camera-specific driver (e.g. Nikon) as only the GPhoto generic driver would work with external shutter release cables. Additionaly, users may employ DSUSB/DSUSB2 from Shoestring Astronomy in order to control the shutter. Before you connect, the port field must be set to DSUSB."

In Ekos Equipment Profile, select GPhoto driver and not Nikon. Save your profile and try again. I'd turn turn off Auto Connect in the profile. Check the Logs button in Ekos summer screen and make sure it is set to Verbose File logging and both INDI + Camera checkboxes are ticked.
After you start the profile, set DSUSB in the GPhoto driver, then go to Options --> Save Config.
Then click Connect and let's see how it goes. Locate (in the same Ekos logs window you can open the logs directory) and then attach the log file here.
