Why was I only able to upload one video from my iPhone?

I uploaded one video from my iPhone onto my YouTube channel just fine. Then, after that, none of them have been able to upload. Does anyone know why that might be?

If you were on your Internet data pack then your data pack pack might be finished that may be the reason, It may be because of the network problem or else may restart your phone. More information on streaming http://www.icecube.no/streaming
