Hi,

$ youtube-dl -F http://www.youtube.com/watch?v=FXsRDxcxmTA | grep m4a

Can you help

[dstftw]

Fix your network connection.

[sebma]

My network is working OK otherwise I would not be able to download other audio DASH format like this one :

$ youtube-dl -f 171 http://www.youtube.com/watch?v=FXsRDxcxmTA

[download] Destination: A_Touch_of_His_Presence_2_Joseph_Prince_Songs__171__FXsRDxcxmTA.webm
[download] 100% of 66.04MiB in 00:34

I'm not saying youtube-dl is reponsible maybe it is coming from another reason :
"YouTube cache servers located in France having issues ?"

Or maybe I have to trick the --fragment-retries parameter ?

[emmtte]

Same problem for me with 100% sure good network

@dstftw I'm also 100% sure my network is OK, please reopen this issue !
