Advertisements I have an issue that started around 5 days ago were my Roamio will not properly communicate with the Tivo service. It will give a C117 error, but there isn't a detectable network issue on my side. I can successfully use apps like YouTube on the Tivo without issue. I have tried both Ethernet and wireless with the same results. I see the Roamio successfully communicating with these IP addresses over HTTP, HTTPS, TCP 8089, TCP 8081: 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206 I don't see any issues with the traffic flow to these IP addresses and no traffic is being blocked on my side. Unfortunately, even though there is a lifetime license on this device it no longer functions as a DVR due to loss of communication with the Tivo service. Is anyone else having communication issues like this? Is this possible related to the new partnership with Channel Master? Any feedback would be appreciated.
