I think you are looking for an earlier one. This shows a restart for an already running observatory. The log we're looking for has this (from your original post)

**Script Error (Tracking has been stopped)**
Source: ACP Observatory Control Software
Message: ==== Startup failed, cannot continue
Location: line 142 column 5.
Script Context:
139: } else {
140: Console.PrintLine("Telescope already connected");
141: }
=> 142: } catch(ex) {
143: Console.PrintLine("**Failed to connect to the Telescope:");
144: Console.PrintLine(" " + ex.description);
145: throw new Error(0x80040001, "==== Startup failed, cannot continue");
-- end --

Actually this looks strange, so please also attach the StartupObs.js script as well as the log with the above error.
