You must run PowerServer Web APIs before you start JMeter recorder (HTTP(S) Test Script Recorder) or Fiddler (or any other Web debugging proxy tool). Otherwise, the PowerServer Web APIs may fail to start.
Reason is JMeter recorder and Fiddler (as well as any other Web debugging proxy tool) work by adding itself as a proxy instead of using your current proxy settings; therefore if the PowerServer Web APIs connects with the NuGet site and Appeon site through a proxy server, it may fail to start.
Keep PowerServer Web APIs running, and close the installable cloud app after you verify that the installable cloud app runs successfully; and then proceed to the next step to record the test scripts.
