Sling will not load today on Roku. Trouble connecting to network. Tried everything listed online to get it going but nothing. Other apps all work
Didnt mention your model # or firmware version, or the specific troubleshooting you did.
Try:
1) Remove the Sling TV app, RESTART THE ROKU (must do this here), re-add Sling TV
2) Network connection reset (Settings/System/Advanced system settings)
3) Check for updates (Settings/System/System update/Check now)
