使用CloudantClient Java API的Cloudant DB的HttpHostConnectException

Question

我正在使用CloudantClient庫連接到Cloudant CouchDB。 此調用不會引發任何異常。 但是在此之后，當我使用CloudantClient進行任何呼叫時，都會收到HttpHostConnectException 。 我嘗試進行諸如serverVersion ， getAllDbs等的調用。這是代碼：

cloudantClient = new CloudantClient(username, password);

//ConnectOptions options = new ConnectOptions();
//options.setProxyHost("myproxy.address.co.in");        
//options.setProxyPort(8080);
//options.setConnectionTimeout(3000);
//options.setMaxConnections(100);
//options.setSocketTimeout(30000);

//cloudantClient = new CloudantClient(username, password, options);     
//cloudantClient = new CloudantClient(username, password);
//cloudantClient = new CloudantClient(username, username, password);
//cloudantClient = new CloudantClient(url, username, password);

System.out.println("Connected to Cloudant");
System.out.println("Trying to fetch metadata from Cloudant");
System.out.println("Server Version: " + cloudantClient.serverVersion());
List<String> databases = cloudantClient.getAllDbs();
System.out.println("All my databases : ");
for ( String db : databases ) {
    System.out.println(db);
}

我正在Eclipse中運行此代碼，並且憑據正確，因為我可以從瀏覽器rest客戶端成功調用。 完整的異常堆棧跟蹤（出於安全原因，我已使用acct字符串替換了日志中的acct / pwd）：

我在異常跟蹤中看到的是某些IP地址被附加到URL： <Account>.cloudant.com/184.173.103.226

我不確定如何以及何時將該IP添加到URL中。 我直接使用Java Cloudant Client API。

誰能提供任何指針/輸入來解決此問題？

在下面添加更新的代碼，以供我嘗試連接的所有差異選項參考-

在下面的ConnectOptions中設置代理后，添加堆棧跟蹤。 我已經用安全性字符串替換了真實帳戶憑據和代理詳細信息。 --

原來，設置代理服務器時HTTP的問題是我們的錯誤（對此感到抱歉）。 我們發布了1.2.1，並修復了此問題。
