Web Video Caster Roku Not Working – How to Troubleshoot

About Web Video Caster Roku Not Working, Web Video Caster is an excellent app that you can use to cast your smartphone content on Roku TV. 

All you need to do is add the Web Video Caster channel on your Roku and install it on your phone or table. 

Then connect the two devices and enjoy a big screen view of videos from your phone’s websites or storage. 

However, there comes a time when this app stops working, which can be frustrating when you want to watch. 

Fortunately, I have researched the possible causes of the Web Video Caster Roku not working and compiled several troubleshooting solutions.

Inspect Your Internet Connection

The first culprit when it comes to Web Video Caster Roku not working is the speed and stability of your internet. 

You should ensure you have a reliable internet connection. In this regard, you need about 5 Mbps for general streaming and more than 20 Mbps for 4K content. 

Therefore, first, check the stability and speed of your WiFi using speed testing tools available online. 

You should also test your connection using a device like a laptop to ensure it’s working. 

While in this step, also ensure your smartphone and Roku media player are connected to the same WiFI.

If you notice any low speed or unstable connection, try restarting your router or modem before reconnecting your app.

 If this does not solve the issues, you may contact your ISP for guidance or information.

Ensure Your Web Caster App is Up to Date

Typically, old app versions can run into errors and bugs that hinder their functionality. 

Luckily, the Web Video Caster developers release updates regularly to ensure the smooth functionality of their app. 

However, you must check for your app updates on the Roku media player and your smartphone. 

To update the app on your Android or iOs operating system, follow the steps below:

  • Visit the Google Play Store or the Apple App Store, depending on your device.
  • Use the search bar to type ‘web video caster’ and run the search.
  • Locate the relevant app and click it.
  • While here, you will notice a link to update your app. Click the link and wait for the update to finish.
  • If you do not find any updating option, your app is up to date.

Now that the phone app is updated, it’s time to update the same app on your Roku using the steps below:

  • Visit the Roku Channel Store or the Google Play store, depending on where you downloaded your Web Video Caster.
  • Now use the search bar to find your app.
  • After you click the relevant app, you will notice an option to update it if it’s outdated.
  • Click on the update link to initiate updates download and installation.

Enable Route Video Through Phone

Sometimes you may notice a black screen when casting videos after updating Chromecast

Also, the app may fail to detect stored videos, and the video buttons stop working. 

While this issue is mostly a Chromecast firmware update error, it may arise even if you have not updated it. 

To go around this challenge, you must route the video through the phone, which you can do in the simple steps below.

  • The first step is disconnecting your smartphone from Chromecast
  • Then launch your webcaster app and scroll to video lists
  • Locate and enable the option to route video through the phone.
  • Now reconnect your phone to Chromecast and check if the problem goes away.

Although we said this is a Chromecast bug that comes after an update, the solution works even if you didn’t update Chromecast. 

The only downside to this troubleshooting is that your phone will drain charge faster than usual.

Perform a Power Cycle on Your Devices

As you may already know, extended electronic device usage can cause bugs and errors, thus hindering web video caster Roku functionality.

 If you have used your device for a long, I recommend a simple power cycle to give your device optimum performance.

 A power cycle is a deep reboot that clears bugs and accumulates static charges in an electronic device. 

To perform a successful power cycle on your smartphone or tablet, follow the steps below:

  • While the process may take hours, you must drain your phone charge to 0%.
  • The next step is to keep rebooting your smartphone using the power on the button. Ensure it is not connected to the charger while rebooting.
  • Once your phone cannot start when you press the power button, connect it to the charger.
  • Now leave it undisturbed and let it charge to full capacity (100%). Do not restart it when charging; if it starts automatically, let it remain in the window.
  • After the 100% charge, let the phone idle for another 30 minutes to build a cache and solve the app reset issues.
  • Finally, reboot your phone, try connecting, and see if you have solved the issue.

After power cycling your phone, I recommend doing the same reboot on your Roku media player.

  • Without switching the socket off, unplug your Roku device from the power source.
  • Put it aside and let it sit idle to clear bugs and static charges.
  • Once one minute is over, replug the Roku device into the power supply and switch it on.
  • Now let it sit in that state for another minute before reconnecting it to your TV and retrying the casting process.

Another obvious solution I didn’t mention is uninstalling and reinstalling the app on both devices.
