Did we lose Fox locals?
What is your provider not enough info.
I ran into this the other day where Fox disappeared on me. I just had to make I was using https://ip:port using the secure link https:// and allowing it to know my location when asked or sometimes it will state on the Not Secure spot in the address bar you can right click to allow location.
Uncheck the Local Networks via TV Everywhere. Then re-check it and it came back for me.
This was with Hulu Live. Hope this works for you.
