This has been happening for a while now where some Youtube videos would return, "The remote server returned an error: (403) Forbidden." Strange thing is that sometime I would get this right away while other times the video proceeds to download then stops giving this error.
I attached the debug log.
Any help would be greatly appreciated.
Your logs indicate that one of many audio segments could not be downloaded and the server returned an error code of 403 Forbidden.
I am unsure why this would happen and have not seen it before.
You could try turning down the max no of segments used: Settings > Internet Downloads > Advanced > HTTP
However I can download that particular video fine here with the default of 5.
