java - Mockserver does not catch my requests -

i trying use http://www.mock-server.com/ mock rest service. source code trying make on: http://metadata.google.internal/computemetadata/v1/project/project-id

i mock service. have written in code:

mockserver = startclientandserver(1080); proxy = startclientandproxy(1090);  new mockserverclient("127.0.0.1", 1080)         .when(                 request()                         .withmethod("get")                         .withpath("/computemetadata/v1/project/project-id"),                 exactly(1)         )         .respond(                 response()                         .withstatuscode(200)                         .withbody("the_project_id")         ); 

when run mock server client , source code makes request, still getting socket exception instead of reply of mock server. how can fix code mock http://metadata.google.internal/computemetadata/v1/project/project-id? have read mock-server documentation not understand well.
