So this morning sometime, after having worked perfectly for 8 months, both of my 2 Minis mysteriously stopped being able to communicate with my Roamio Plus. My internet, MoCA network, and the Plus seems to be working completely normal otherwise. Both Minis say that their network connection status is fine, and both are able to connect to the TiVo servers normally. They just aren't able to connect to the host DVR. All 3 units have lifetime service, and say their service is active, both in their settings and on the TiVo website. I've tried restarting all units multiple times, as well as restarting my cable modem, router, and MoCA adapter. I've even tried connecting the Plus and a Mini directly to my router via ethernet. The Mini can still call into the TiVo servers successfully but can't communicate with the Roamio. In the Mini settings, it says the host DVR is "UNKNOWN". I'm thinking this has to be some problem with the TiVo service itself, but the TiVo status website hasn't reported any service outages. I haven't called TiVo yet, but I'm thinking I will have to, since I have run out of things to try. Anybody else have any ideas?
