Hello Yana,

Can you enable the client logger and send the output to support@lightstreamer.com?

You can enable the logger by adding the following lines to your application:

var log = new SimpleLoggerProvider();
log.addLoggerAppender(new ConsoleAppender("DEBUG", "*"));
LightstreamerClient.setLoggerProvider(log);


Which server version are you using?

Are you using a single Lightstreamer server or a cluster behind a load balancer?

Have you configured a control link address for your Lightstreamer server?

Regards
