app.lightstreamer.com is Refusing Connections to Validate Trial Licenses

Since restarting my demo version of Lightstreamer at 11:09 this morning BST I have been getting the flowing message repeated every 5 seconds in the log:

ERROR|LightstreamerLogger.license |main |IO Error occurred: java.net.ConnectException: Connection refused: connect
FATAL|LightstreamerLogger.license |main |Can't connect to remote license server.
FATAL|LightstreamerLogger.license |main |Can't validate the trial license System exits.

Is the license server experiencing issues?

Thanks,
Steve

Hi,

the server (machine) was up while the server (process) had some issues.
It should be back to normal now

Cheers; it's all working now.

yeah I confirm, it is 100% working now.
