I have a new 55b7 that I've just purchased. Live TV and external sources on HDMI are working fine, successfully upgraded Firmware to 4.70.6 over Wireless, web browser works fine. Freeview play works for future programs but attempting to look backwards temporarily displays a '''requires agreement" form which vanishes before I can do anything. Internet apps all 'require upgrading' but always fail to do so with a 'Temporary' LG content store timeout. Tinkered with DNS settings, rebooted TV and router (Plusnet fibre) with no improvement. LG content app always fails with the timeout.
Web searches suggest LG is doing something unusual with the content store internet connection, perhaps it attempts to make an inbound TCP connection or some unusual port mapping is required.
Any body seen a solution for such a problem?
