    Default Restart Wowza

    Hey Everyone!

    I am with a problem that when I restart the Wowza Server in Wowza Streaming Engine he doesn't work more. Acessing http://[wowza-ip]:1935 the server isn't found. Acessing Wowza Streaming Engine and trying to add stream the message is shown:
    "MediaCaster type not found[live/_definst_]: rtp"
    Can anyone tell me what can be? Would it be a bug?

    Because i saw in Release Note [] that this issue ["Fixed RTP MediaCaster thread locking issue with application instance shutdown"] was corrected.

    P.S: Wowza Streaming Engine version 4.0.4 in AMI (Amazon Machine Images) with license Byol.
    AMI ID: WowzaStreamingEngine-ebs-byol-4.0.4-x86_64-5f03c7f6-de9b-43fe-a602-1c49f77d1a02-ami-1e847d76.2 (ami-574ae54a)

    Hello there,

    Are you sure you restarted the stream upon Wowza restart? How are you starting the stream? /conf/StartupStreams.xml or from Stream Manager?

    Hello Salvadore,

    Yes, i have. Indeed i restart the Wowza service in Wowza Streaming Engine Interface and it stopped to work. I start the stream by Stream Manager too. When i try to access http://[wowza-ip]:1935 informations like "Wowza Streaming Engine 4 Developer Edition 4.0.4 build[numbers_here]" are not displayed.

    Lets see what the logs have to say, start Wowza in stand alone mode, [install-dir]/bin/startup.bat( on Mac)

    This will display the logs in the console. Do you see any start up errors in the logs?

    i see that the error happened in HTTPProvider created by me. But i create in a development environment with the same Wowza version. What would be a "Unsupported major.minor version 52.0"? Java version?
