The Icecast Mailing Lists (and their archives) are one of the first places to check for questions that may have been answered in the past.
We have two mailing lists devoted to Icecast:
[icecast] mailing list is appropriate for general icecast usage questions.
[icecast-dev] mailing list is reserved for any developer related questions.
Then simply follow the directions from there.
The official ways to report bugs are to send a message to the
icecast-dev mailing list,
submit a bug report to https://gitlab.xiph.org/xiph or alternately go to the #icecast IRC channel.
Please submit this information in one of these ways.
Email the webmaster if you notice a broken link, outdated or inaccurate information, or another flaw on icecast.org. For questions, use the mailing list above.
