My project has a OCR requirement and I want to use the google cloud Vision API. I download the sample code via GIT, but it report follow errors:

Exception in thread "main" java.net.SocketTimeoutException: connect timed out at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:85) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at sun.security.ssl.SSLSocketImpl.connect(SSLSocketImpl.java:668) at sun.net.NetworkClient.doConnect(NetworkClient.java:175) at sun.net.www.http.HttpClient.openServer(HttpClient.java:432) at sun.net.www.http.HttpClient.openServer(HttpClient.java:527) at sun.net.www.protocol.https.HttpsClient.(HttpsClient.java:264) at sun.net.www.protocol.https.HttpsClient.New(HttpsClient.java:367) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.getNewHttpClient(AbstractDelegateHttpsURLConnection.java:191) at sun.net.www.protocol.http.HttpURLConnection.plainConnect0(HttpURLConnection.java:1138) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:1032) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:177) at sun.net.www.protocol.http.HttpURLConnection.getOutputStream0(HttpURLConnection.java:1316) at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:1291) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getOutputStream(HttpsURLConnectionImpl.java:250) at com.google.api.client.http.javanet.NetHttpRequest.execute(NetHttpRequest.java:77) at com.google.api.client.http.HttpRequest.execute(HttpRequest.java:981) at com.google.api.client.auth.oauth2.TokenRequest.executeUnparsed(TokenRequest.java:283) at com.google.api.client.auth.oauth2.TokenRequest.execute(TokenRequest.java:307) at com.google.api.client.googleapis.auth.oauth2.GoogleCredential.executeRefreshToken(GoogleCredential.java:384) at com.google.api.client.auth.oauth2.Credential.refreshToken(Credential.java:489) at com.google.api.client.auth.oauth2.Credential.intercept(Credential.java:217) at com.google.api.client.http.HttpRequest.execute(HttpRequest.java:868) at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.executeUnparsed(AbstractGoogleClientRequest.java:419) at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.executeUnparsed(AbstractGoogleClientRequest.java:352) at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:469) at com.google.cloud.vision.samples.label.LabelApp.labelImage(LabelApp.java:136) at com.google.cloud.vision.samples.label.LabelApp.main(LabelApp.java:71)

I don`t modify any code and I could get the successfully test results on the API browser explorer. Has anyone met this kind of issue before?Could you please give me any suggestion?

    I test the demo from China, is it possible because of the network restriction? I already setup a VPN connect and I could access the Vision API explorer test page and perform the testing. Can anyone give me any suggestion? – claire mao Jan 14 '17 at 12:44

java.net.SocketTimeoutException means the connection timed out before a response was received from the remote host. This is almost always caused by local network issues, or proxy or firewall configurations.

I solved this by setting proxy mode to global mode
