If you are experiencing problems using the communication features within the event, such as not receiving new message notifications or being unable to send text in a chat window, it may be due to the configuration of your company's network. Certain firewall configurations can prevent the communication features from functioning properly. Proxy servers and application-layer firewalls are designed to filter content based on rules that are set up by the system administrator. The wide variety of rules means that non-HTTP traffic such as RTMP (Real-Time Messaging Protocol) may have trouble getting through some servers. If the connections can’t get through, you should contact the administrator of your organization’s firewall to see if he or she can make an exception. Adobe Flash over "fallback" port 80 can still be blocked and/or filtered based on Proxy Servers, Web Filtering Software (Websense, Smartfilter, etc.), Intrusion Detection/Prevention Systems (IDS/IPS), application layer firewalls, and other unique network configurations. If you are using a Proxy Server filter, make sure you aren’t filtering out application/x-fcs.
If a yellow flag displays in the chat window, your port 1935 is being blocked and you are using port 80.
