I have been looking at posts and have seen some very similar topics but we had something slightly different happen with a webcast at our stake conference with Elder Holland as our guest General Authority.
We lost audio and video to our remote meeting house four times with about a four minute recovery each time. Many upset members... What would happen is the Internet led on the communicator box would go red, then back to green then the error led would come on. The error message "link failure:press

to restart". The restart would take four minutes before the box restarted and we had data back to the other building. It seems the webcast communicator is very sensitive to an upload interruption.
Has anyone else had this issue and if so were you able to resolve it?
Thanks in advance.
