This is just a heads-up that there are scammers/fraudsters out there offering “worldwide protection” against Trojans and viruses, because that’s why you can’t set-up your new Plex server on Firestick TV devices.
I experienced this today. I added a new Firestick to a new TV, and thought I’d connect to my server by signing in. I was prompted to get online and use a 4 letter code to authenticate my new setup. “plex.tv/code” is I believe the correct address, but I think I enter “plextv.com/code” or something similar… i.e. minor typo. I was taken to an authentic-looking Plex page, where I entered my code and got a “failed connection” warning with several possible reasons, most implying that hackers had gained access to my home network. I dialled the 1-800 number provided and was told that all of my devices were infected and for $100/year up to $400 for 5 years I could get worldwide protection by a national security agency for current and future hacking problems! The scam was obvious to me and I hung up, but probably not so obvious to some. I wish I would have written down the actual URL I was forwarded to, but, sorry, it was too late after I overwrote the same browser tab, when I tried again with the correct Plex URL. My phone log shows the 800 number was 888.521.0954 for what it’s worth.
I hope this is helpful to someone!
