I have three set-top boxes in CP. One main evobox hd and two multiroom evobox lite. On one decoder there is a message that the decoder has been blocked and to check the LAN WiFi connection with the main decoder. Second same decoder and master decoder work fine. I hung for hours on the hotline, did factory resets, did a hotline reset and told me to wait 3 to 6 hours and then the same. I changed the Wi-Fi router to another one and logged all decoders on it and this one is still blocked and it says that it does not see the main decoder in the network. I replaced the set-top box with a new one at CP and it was ok for a while, the TV was playing, but it did updates itself again and it locked again. Overall, the problem started when the decoder updated itself. The other decoder that works does not update. I have no idea where the cause is anymore. Does anyone have the same problem as what to do?
