com.sun.mail.util.MailConnectException: Couldn't connect to host, port: imap.gmail.com, 993; timeout -1; Exception while connecting to gmail in windows remote machine through automation scripts

Hi Team,

In my automation script i have to connect to gmail and validate the received email. Below is the code used to connect to gmail and validate the received email.

public static void newemailNotification(String gmailUserName, String gmailPassword,
String sub, String sRid, String rRid,
String reference, String noOfDocs) throws MessagingException, IOException
{
Properties props = new Properties();
props.setProperty("mail.store.protocol", "imap");
props.setProperty("mail.imaps.partialfetch", "false");
props.put("mail.imap.ssl.enable", "true");
props.put("mail.mime.base64.ignoreerrors", "true");

Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imap");
store.connect("imap.gmail.com", 993, gmailUserName, gmailPassword);

Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
Message[] messages = folder.getMessages();

for (Message mail : messages) {
if (!mail.isSet(Flags.Flag.SEEN)) {

String[]mailContent=mail.getContent().toString().split(":");
String subject = mailContent[1];
LOGGER.debug("Subject:" + mailContent[1]);
String ref = mailContent[4];
LOGGER.debug("Reference:" + mailContent[4]);
String doc = mailContent[5].trim();

LOGGER.debug("Actual:" + sub);
LOGGER.debug("Expected:" + subject);

Assert.assertEquals("Actual: " + sub.trim()+" Expected:" + subject.replace("Sender RID/Extension", "").trim(),sub.trim(), subject.replace("Sender RID/Extension", "").trim());

But i am receiving the exception  at the line store.connect("imap.gmail.com", 993, gmailUserName, gmailPassword); as follows

com.sun.mail.util.MailConnectException: Couldn't connect to host, port: imap.gmail.com, 993; timeout -1;
