I'm trying to run these samples in colab, but it throw this error:

Waiting for authorization and callback to: http://127.0.0.1:8080/...
Traceback (most recent call last):
  File "/content/v1/list_apps.py", line 81, in <module>
    main()
  File "/content/v1/list_apps.py", line 76, in main
    service = admob_utils.authenticate()
  File "/content/v1/admob_utils.py", line 99, in authenticate
    code = _get_authorization_code(passthrough_val)
  File "/content/v1/admob_utils.py", line 129, in _get_authorization_code
    sock.bind(("localhost", PORT))
