Don’t know if Anyone can help but will give it a try. l was getting an internet channel called Throwback TV that I had in a playlist in Tivimate. The other day the owners of the channel changed their address to get the channel. They gave me their new address but it won’t work. I use the send file to tv app. I put the file in my iPhone storage and send it to my Nividia shield pro. This has worked every time I have tried this but I keep getting an error303 or 404. Is this a Nividia shield problem or something else. Does anyone have any knowledge about this.
