I have been successfully using IPTV for several month now but since I moved to a new ISP and router (Fritz!box 7530) it stopped working. It is loading all the channels nut when I select one I am getting 'Cannot open URL'. I have called my new ISP and they are telling me they are not blocking anything. My wild guess is that it is a setting in my Fritz!box 7530. Can anyone help me or point me in the right direction? Thanks in advance.
