If you use Deep Packet Inspection on your firewall, check that it supports WebSockets and the WSS protocol. If there are issues loading the meeting room it could be that the Deep Packet Inspection is breaking the security model of WebSockets. If this is the case please put an exemption for our domain in your Deep Packet Inspection configuration.
