Error raised when trying to connect to Lightstreamer.

Gregor

Hello, I am trying to connect to Lightstreamer using the https://labs.ig.com/sample-apps/api-streaming-companion-release/index.html page, but I always get the error:

Connecting to Lighstreamer: https://demo-apd.marketdatasystems.com loginUtils.js:121 LSS login Z60VWW - CST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX|XST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX loginUtils.js:94 Lightstreamer client - start listening loginUtils.js:94 Lightstreamer connection status:CONNECTING lightstreamer.js:175 POST https://demo-apd.marketdatasystems.com/lightstreamer/create_session.js 500 (Internal Server Error) lightstreamer.js:214 WebSocket connection to 'wss://demo-apd.marketdatasystems.com/lightstreamer' failed: WebSocket is closed before the connection is established. loginUtils.js:94 Lightstreamer connection status:DISCONNECTED:WILL-RETRY

One month ago everything was working fine. Has something changed?

To investigate, server side information from IG would be needed.
I can only remark that create_session.js is part of an ancient JDK version.
However, this should not be the cause of the error, since all versions of Lightstreamer Server support all previous SDK versions.
