It says the input URL is not reachable so either you have the wrong host name, wrong port number, or the IS that is supposed to be running behind that port number (7777) is not running.
I’m not familiar with this VM but that’s my guess. Is LocTrain220905 the host name of the virtual machine you’re on? If you open a browser and go to http://LocTrain220905:7777, are you prompted for a login for the IS Administration console? I’m guessing you won’t be due to the error you’re receiving. What happens if you go to http://localhost:7777? You can also run netstat -an | findstr 7777 on the command prompt to see if that port is open.
If it’s not, then you will need to start the IS that is supposed to run under that port. It could also be that the IS is running but on a different port. In that case, you could find the process ID that the IS is running under and then use something like netstat -ano | findstr pid to find the port number. It’s possible (perhaps even likely) you have multiple IS’ running though, for example, one for APIG and a separate one to host the web service so keep that in mind.
