If you are trying to stream to a Youtube Event and are getting a red error stating ' User Blocked from Streaming' then you must make sure that you have more than 1000 subscribers on the account you are trying to stream to. Unfortunately Youtube put a restriction on accounts, with less than this limit, which doesn't allow them to stream using mobile devices. Below you will find an article explaining this further.
While we work on getting this resolved please note this does NOT effect the Stream Now option nor does it effect our Generic RTMP option, which could be used as a workaround for streaming to events. To do this you can input the events RTMP credentials manually into the Generic RTMP section. If you have any other questions please contact support for more help.
