If you are using BUTT to stream to your server then we recommend you update to the latest version as soon as possible. Outdated versions of BUTT (0.1.15 and lower) don’t work with the latest version of Shoutcast (2.5.5).

Please download the latest version 0.1.16 here:

EDIT: We have made this post sticky again as some customers are still using the old version of BUTT and unable to connect when updating Shoutcast.
