Before moving on with the solutions, check if your network is working fine. Moreover, check if switching between ethernet or Wi-Fi (after disabling the other type) solves the issue. Also, check if disconnecting all other devices from the network (except the Apple TV) and launching the Hulu app resolves the issue (if so, then check which device on the network is conflicting with the Apple TV/Hulu). Additionally, make sure Apple TV is compatible with the Hulu app.
Force Quit the Hulu App and Relaunch it
A temporary malfunction of the Hulu app may stop it from working and relaunching the app after force quitting Hulu may solve the problem.
Power Cycle Apple TV and Networking Equipment
A temporary glitch of the Apple TV may stop the Hulu app from working and restarting the Apple TV may solve the problem. If that did not work, check if powering off the Apple TV with any other content playing (not Hulu), powering on the TV, and launching the Hulu app solves the problem.
Update the Hulu App to the Latest Build
An outdated Hulu app may cause incompatibility between the Hulu app and other modules of the Apple TV, which leads to the issue at hand. In this context, updating the Hulu app of the Apple TV to the latest build may solve the problem.
Reinstall the Hulu App
The Hulu app may encounter the issue at hand if its installation is corrupt and reinstalling the Hulu app of the Apple TV may solve the problem.
Update the Apple TV’s Firmware to the Latest Build
The Hulu app might not work on the Apple TV if the firmware of the TV is outdated (as it may cause incompatibility between the TV modules and the Hulu app). In this case, updating the firmware of the Apple TV to the latest build may solve the problem. If the issue started after a firmware update of the Apple TV and there is no more update available, then check if downgrading the firmware of the Apple TV solves the issue.
Edit the Apple TV’s DNS Settings
The Hulu app might not work if the DNS settings of the Apple TV are not properly configured or using a non-default DNS (due to which your network could not resolve the web addresses of the Hulu servers). In this context, reverting the DNS settings of the Apple TV to the default may solve the problem.
Disable the 4K Feature in the Apple TV Settings
The Hulu app might not work if the 4K is enabled in the Apple TV settings (supported models only) and disabling the 4K feature of the Apple TV may solve the problem.
Update the Router Firmware to the Latest Build
The Hulu app may show the issue under discussion if the firmware of the router is outdated as it may become incompatible with the Apple TV or Hulu app. In this case, updating the router firmware to the latest release may solve the problem.
Remove the Conflicting Apps from the Apple TV
The Hulu app might not work on the Apple TV if an app on the Apple TV conflicts with the Hulu app and removing the conflicting applications (especially streaming apps) may solve the problem. The Netflix app is reported by users to cause the Hulu issue at hand.
Reset the Apple TV to the Defaults
The corrupt firmware of the Apple TV may stop the Hulu app from working and resetting the Apple TV to the defaults may solve the problem. Before moving on, make sure to back up the essential info/data as everything will be wipe cleaned.
