Alexa media player unable to read external mp3

I can’t play an external mp3 on my echo dot even though the google mini can play it without any problem

In addition to having problems with local mp3, now it’s an mp3 on a site I think is secure

service: notify.alexa_media
  message: <audio src='' />
  target: media_player.echo_dot_carlier
    type: tts

have you a solution ??
