Error trying to ping server when trying to play_media

[dashboarddave]

Everything seems to be functioning fine except when I actually try to play a movie using client.play_media(). It gives the following message...
Error trying to ping http://10.0.1.124:32400/system/players/machine name/application/playMedia?path=http%3A%2F%2F10.0.1.124%3A32400%2Flibrary%2Fmetadata%2F445&key=%2Flibrary%2Fmetadata%2F445 - 500 Internal Server Error

Not sure if it is a issue or if I am doing something wrong. I can pull all other info from the server as the instructions state. But .play_media() gives me that error. Can someone chime in and give me a little help. I would really appreciate it. Thank you.
