Java Websocket client running on linux VM not able to receive response from Websocket server - spring-boot

Question

I have a Java websocket client and server developed with spring-boot. Websocket server deployed in pod .
When i try connecting my wss server from my eclipse console and windows terminal i am able to receive message from server but on the other hand no server response received when i run the client from a linux vm
I am really stuck. Any help will be appreciated.
**Java Client Code:**
public void connectPlain() throws InterruptedException, ExecutionException, IOException {
WebSocketHttpHeaders header = new WebSocketHttpHeaders();
header.set("IDS-SESSION-ID", sessionId);
this.session = new StandardWebSocketClient().doHandshake(new TextWebSocketHandler() {
#Override
public void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
log.info("Server Session {} " , session.getId());
session.setTextMessageSizeLimit(100 * 1024 * 1024);
log.info("Ack from Server:: {} " ,message.getPayload());
}
#Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
log.info("Client Session {} " , session.getId());
}
#Override
public void afterConnectionClosed(WebSocketSession session, CloseStatus status) throws Exception {
}
}, header, URI.create(url)).get();
if(this.session.isOpen()) {
while(true) {
log.info("Session Open ****");
session.sendMessage(new TextMessage("Client-"));
Thread.sleep(10000);
}
}
}
**Websocket Server Code**
public class SocketHandler extends TextWebSocketHandler {
ConcurrentWebSocketSessionDecorator cws;
#Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
session.setTextMessageSizeLimit(100 * 1024 * 1024);
log.info("Connected... with messageBufferSize :: {},{} ", session.getId(), session.getTextMessageSizeLimit());
cws = new
ConcurrentWebSocketSessionDecorator(session,3000,100*1024*1024);
}
#Override
protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
String tenantId = session.getHandshakeHeaders().getFirst("tenantid");
log.info(message.getPayload());
session.sendMessage(new TextMessage("Ack From server"));
}
