I built Wowza Streaming Engine 4.0.6 on EC2, and am trying to publish live stream from Elemental Live hardware encoder.

I made sure that the Wowza server works well with GoCoder app, but doesn't work with Elemental Live hardware encoder.

According to the error log on Elemental Live encoder,

2014-08-19 07:54:15 I RTMP mediaID [25] successfully connected to server [Connection succeeded.] [FMS/3,5,7,7009] []

2014-08-19 07:54:15 I RTMP mediaID [25] connection message [NetStream.Publish.Denied] [RTMP Publishing not allowed. Client is not in list of valid encoders.] [] []

It seems that the hardware encoder is denied from valid encoder list. I couldn't find any info about the valid encoder list on the Internet. How can I make my encoder allowed to publish?

Thanks
