Firstly, thanks for the help and efforts on this - i do realise it's a bit of an "edge case" but, as you say, although it may be unique today it's probably uncovering some odd bufering issue which might show up for others and also as we all transition to cloud, others will probably come across this as well - it doesn't make sense $ wise to store and backup large amounts of media locally anymore (for me) and with high speed broadband connections now becoming so widespread, storing the data in the cloud is just the way forward as far as I can see. So, to take out some of the variables, I've messed around a bit and managed to get an IP address on the server this which looks like it comes from the UK. Now AbsoluteRadio, which was blocked before, plays quite happliy. So, at least some services think the server is now UK based. However, when I try and play BBC Listen Live I just get complete silence and it stops after a couple of seconds. Listen Live (Non UK) still the same - a couple of seconds of play normally, then it stops - and the players show "buffering". For the UK streams, the log file is attached, but it using the url it fails at, if i try and open it directly, i get Access Denied You don't have permission to access "http://as-hls-uk-live.edgesuite.net/pool_6/live/bbc_radio_five_live/bbc_radio_five_live.isml/bbc_radio_five_live-audio%3d320000.m3u8?"; on this server. Reference #18.2487b5c.1429875964.69556fee So - I guess this means that BBC still thinks i'm outside the UK - grrrrr. Any thoughts on that? I can spin up a linux VM in the cloud to test if this is a windows specific problem - I'm no linux expert, but will muddle my way through. Is there a preferred linux flavour to try and if so, can someone point me at the right LMS to download for it (and if anyone had a quick guide on how get it running, even better) Is a Pi server upto doing the necessary transcoding for high bit rate streams? If so, I may go down that route, and just have the media library remote. Any differences on the Pi versions - I already run a couple of Pis for squeezelite - has anyone run the server and squeelite on the same Pi, or should I dedicate one if I try that? +-------------------------------------------------------------------+ |Filename: server BBC UK.log | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=17926| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ psketch's Profile: http://forums.slimdevices.com/member.php?userid=56555 View this thread: http://forums.slimdevices.com/showthread.php?t=53229
