Not quite sure when this started.

Errors are:

<07/30/17@15:33:38> [dest: 37.59.25.124] starting stream (UID: 0)[L: 1]{A: SHOUTcast Directory Tester}(P: 0)
<07/30/17@15:33:39> [yp_add] yp.shoutcast.com gave error (nak)
<07/30/17@15:33:39> [yp_add] yp.shoutcast.com gave extended error (Cannot see your station/computer (URL: http://210.54.38.171:8000) from the Internet, disable Internet Sharing/NAT/firewall/ISP cache - see http://wiki.shoutcast.com/wiki/SHOUTcast_YP_Nak_Errors [480])

I do know that some time ago Shoutcast v1 stations were de-listed from the directory. I suspect this is related. I have same errors in my logs.
