Bokeh items are not rendering due to websocket connection failed

Launching a panel web application using bokeh commands. Part of which it used to worked fine when using the IP address and port number on python script and on the service. However, somehow, it stopped working on some machines that are connected to the network and is only working on one remote machine on Firefox and not on Chrome. Any explanation to this? I tried setting up the argument (–allow-websocket-origin) to * to make it easier for access. Same problem persists. It was working fine, it currently renders blank template for other machines/users.
