I've been using the same custom RTMP setting to stream to YouTube at 720p. The last successful event I did was Oct. 19th. Yesterday I tried to stream in the same way by adding the stream name for the event created and using the proper primary server url. I also tried the background server url. Both times I would get a "can't read from RTMP server. Connection lost" or it might have been connection terminated. I tried rebooting the computer and building a new custom streaming profile with no luck. I'm wondering what changed since Oct. 19th? Any help would be appreciated.
