An attendee experiences connection, video, audio or transition issues in an Adobe Connect meeting.
Adobe Connect presentations are normally delivered as HTTP data on port 80, while meeting audio and video streams are delivered as RTMP data on port 1935. When users are inside a corporate firewall that blocks these optimal ports, Adobe Connect uses fallback mechanisms to deliver RTMP data on ports 80 and 443. This fallback technology is called tunneling. This tunneling mechanism results in additional overhead that impacts overall throughput and the end user experience
Have the attendee switch to a computer on a network that does not block the preferred Adobe Connect ports.
