坐在我公司的代理服务器后面，我遇到了困难，访问了Google Speech API。
我的代码如下（从谷歌的示例中复制和修改）：
System.setProperty("http.proxyHost", "x.x.x.x");
System.setProperty("http.proxyPort", "xxxx");
System.setProperty("https.proxyHost", "x.x.x.x");
System.setProperty("https.proxyPort", "xxxx");
FileInputStream credentialsStream = new FileInputStream("C:\\Path\\To\\Credentials.json");
GoogleCredentials credentials = GoogleCredentials.fromStream(credentialsStream);
FixedCredentialsProvider credentialsProvider = FixedCredentialsProvider.create(credentials);
SpeechSettings speechSettings = SpeechSettings.newBuilder().setCredentialsProvider(credentialsProvider).build();
try (SpeechClient speechClient = SpeechClient.create(speechSettings)) {
RecognitionConfig.AudioEncoding encoding = RecognitionConfig.AudioEncoding.LINEAR16;
int sampleRateHertz = 16000;
String languageCode = "de-DE";
RecognitionConfig config = RecognitionConfig.newBuilder().setEncoding(encoding)
.setSampleRateHertz(sampleRateHertz).setLanguageCode(languageCode).build();
String uri = "C:\\recordings\\testRec16hz.wav";
RecognitionAudio audio = RecognitionAudio.newBuilder().setUri(uri).build();
RecognizeResponse response = speechClient.recognize(config, audio);
}
收到以下错误：

我认为响应可能来自代理服务器，因此谷歌sdk无法读取。
当我在没有设置代理属性的情况下运行时，我会在一段时间后得到以下内容：
com.google.api.gax.rpc.DeadlineExceededException: io.grpc.StatusRuntimeException: DEADLINE_EXCEEDED: deadline exceeded: -115304848173 ns from now
如何阅读回复以获取更多信息？ 我该如何处理 - 是否需要联系代理服务器的管理员？
