    Hello there.

    Are you experiencing any streaming problems?

    Can you provide any more detail about your setup?

    Are there anymore error messages in the logs leading up to this message?

    Kind regards,

    One other suggestion would be to enable UDP port sharing as this multicast listener error might be related to the RTP port binding:
    How to enable UDP port sharing (unicast and multicast)

    Its just a guess, but this may make the error go away.

    Kind regards,

    Salvadore

    Just noticed
    I can not receive multicast on Wowza
    Multicast is avialable on server
