nGrok error when I using trape

File "/usr/lib/python2.7/subprocess.py", line 223, in check_output
raise CalledProcessError(retcode, cmd, output=output)
CalledProcessError: Command '['./ngrok', 'http', '80', '-log', '86bc06c.nlog']' returned non-zero exit status 1
[x] ERROR:
---=[ We can't connect with nGrok

Start by reproducing the reported command, ./ngrok http 80 -log 86bc06c.nlog, through the Python 2.7 subprocess path. Inspect the nGrok connection failure and determine the conditions needed for Trape to connect successfully; done means the command no longer exits with status 1 and the connection error is resolved.
