You are not able to connect using long-polling, but you can using
callback-polling.

This typically means that you have a cross-origin setup, but you have
not configured the cross-origin filter properly.
See https://docs.cometd.org/current/reference/#_javascript_transports_cross_origin
and https://docs.cometd.org/current/reference/#_java_server_configuration_advanced_cross_origin_filter.
