Then after many hours over two days, seemingly from out of the blue, the Ooma installation completed and I got the desired solid blue light. I thought this was the result of my persistence in cycling, recycling, and trying suggestions from this forum. But it turns out that one of the Ooma techs I contacted knew what the problem was. At least that is what he told me in an email:
"Your network blocks SSL traffic as a result of which Telo could not download the home security software, so I manually installed it. That's what fixed the problem".
I'm not sure what this all means. Does this mean he was able to remotely install software on my Telo without my knowledge or permission? Of course, I would have granted permission if I thought this would fix my problem. Also, what is this business about my network blocking SSL traffic? My network is a Google Nest Mesh Wifi system. I've done nothing to block SSL traffic. Any ideas how to fix this blocking? Thanks.
