I encountered a strange situation: in public sector, there is a isolated network (wifi-5g ap-router-modem, made by oppo branded by wireless career, one Linux desktop connected with Ethernet to oppo router, one android tv connected over wifi and employee owned phones connected over wifi). The unusual problem is that regarding of network settings (dns, 2.4/5ghz and so on) YouTube does not work on tv but works everywhere else. TV shows that network has limited access and does not load YouTube app (but loads Netflix app). YouTube is available on both desktop over Ethernet and phone over wifi. Curl on Linux desktop shows proper http response to youtube site. Router control panel is accessible and does not contain any unusual entries that might block yt access on tv. Do you have any idea how youtube might be blocked on tv?
