Thank you! They’re describing the exact same problem I’m having. I figured it was a Firewall creating the issue. I enabled Home Network Protection via the My Fios app a couple of months ago. It doesn’t currently have a whitelist for domain names, but it does have an option to disable specific devices, which did the trick. I suppose Fios uses a list from McAfee for the Home Network Protection feature on their routers. They must be trying to prevent piracy without taking into account legal usage of Plex Media Server.
