Error Connecting
Sorry, an error occurred while opening a client connection: While initializing global variables: an error occurred on the business tier: An error occurred while receiving the HTTP response.
This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down)

Please log as the admin of ELN and search for the user affected and look at the offline folder and remove all the folder/notebook or experiments.
