These streams all refer to https://mapr.box.com/shared/static/(something).mp3 but nothing returns from the URL.
NSlookup shows three addresses:
mapr.box.com has address 220.127.116.11
mapr.box.com has address 18.104.22.168
mapr.box.com has address 22.214.171.124
and the IP-address can be accessed, but then the webserver replies
Your request on the specified host was not found. Check the location and try again.
so it seems the webserver configuration is not correct.
Please look into this
