Websocket connection failed error.

Hi Team,
We are trying to connect to SOLACE system to access Queue using Java Script. For some reason Javascript
is giving following error.

“Websocket connection failed error. Error during websocket handshake”.
Please advise.
Thanks
Rahul

Which API and which version? If using the Solace native JS API, please ensure you have an up-to-date version, as Guaranteed messaging support was added later. https://solace.com/downloads/?fwp_downloads_types=messaging-apis-and-protocols
