Problem(s) Encountered:

Tried to use the Rotator GUI, but whenever I tried to send a rotation, it responded with an error message. Found out I couldn't use the hand paddle in the dome either. So I reset the box on the telescope and I regained hand paddle control.  I thought the GUI might work after the reset too, but I got the same error message that read:  Error: couldn't open socket: host is unreachable.  Didn't lose time over this, but there were small rotations I had to make in the dome I would’ve rather made with the GUI.

Solution:

Power-cycled the port server.  Resolved.
