Troubleshooting Prerequisites

Before you start troubleshooting and looking for complex solutions, make sure you satisfy the requirements listed below.

Server Outages

Check for any server outages for Hulu. If there is one, the only thing you can do is wait until it’s over, which will not take long. Also, it is not uncommon for streaming platforms to encounter such outages, so this is an important step.

A Consistent Internet Connection

Make sure your internet connection has a minimum speed of at least 5MBP/s to ensure that the problem does not root from a poor network connection. You can perform an internet connection test by reading our article written by Talha Saeed, a tech geek.

Disable Any VPN Or Proxy

If you are using any VPN or Proxy that changes the public IP address of your computer, you won’t be able to access Hulu services. Ensure that these security measures are turned off when you access Hulu.

Use Only One Devise For The Time Being

Just as a precaution, power off all devices, and use Hulu on only one device. This is only for the time being and is just a precautionary measure. You can turn the rest of the devices off later.

Restart The Device And Router

If an app module or a required one is stuck in operation, this can lead to the Hulu dev 340 error. In such a case, restarting the device and router will solve the problem.

  1. Power off the device and router. Also, power off other devices such as a Firestick or TV (if being used).
  2. Unplug the power cables and wait for a minute.

Try Another Port And Cable

If the port on which the device is connected or the cable is faulty, it can affect Hulu’s ability to correctly show the output and this can lead to the dev error. Here, trying another port and cable will do the trick.

  1. Restart the device and TV.
  2. Without launching Hulu, disconnect the device from the TV and use another HDMI cable to another port on the TV.

Try Another Network

If your ISP restricts Hulu’s access to an essential online resource, this will cause the app to show error 340. This can be fixed by trying another network.

  1. Disconnect your device from the network in the use and restart the device.

    Enable the Phone's Hotspot
    Enable the Phone’s Hotspot
  2. Connect to another network (e.g., a phone’s hotspot) and launch Hulu. See if it is working correctly. If so, then either your ISP or a router setting is causing the issue.

  1. Launch a web browser and go to the account page of the Hulu website.
  2. Log in using your credentials and go to the Your Account section.
