Unable to upload a track using the soundcloud API larger than 7MB

I am unable to upload any tracks larger than about 7MB (413 Request Entity Too Large is returned). This functionality was previously working and the soundcloud api states that tracks can be upto 500MB.

Here is an example using curl with a successful upload(4.9MB) and an unsuccessful one(7.4MB)

I have provided dropbox links to the tracks(my own production, so no copyright issues!!!) if anyone wants to try to replicate. You will need to add your oauth_token.

successful upload = 4900kb_307sec_128kbps_44100hz.mp3

curl -i -X POST "https://api.soundcloud.com/tracks.json" \
           -F 'oauth_token=********' \
           -F 'track[asset_data]=@4900kb_307sec_128kbps_44100hz.mp3' \
           -F 'track[title]=A 4.9MB track' \
           -F 'track[sharing]=public'

We have the same issue with soundcloud. Seems to be an issue in their nginx.conf (webserver configuration).

Please contact Soundcloud support for developers.

Was an issue in SoundCloud API routing. Has been fixed now.

For details see comments at: Soundcloud: increased 413 failures (Request Entity Too Large) on upload
