When you are ready to watch Paramount Plus, but encounter an error code 3304. That is very disappointing. You may want to know what this code means, what causes this code, and how to fix it so you can watch your movies.  In this article, I will answer all the questions and help you with multiple ways to fix it.

What Is Error Code 3304?

Paramount Plus error code 3304 is a common streaming media error, which mainly indicates interruptions between the server and the device. When you use Edge, Firefox, or Xbox, kinds of devices to play movies, the error would occur if the security verification process cannot be finished.

Common Causes of Error Code 3304

Although this error code is often associated with connection failure, the real reasons are usually hidden behind the device’s settings and the internet environment.  Hence, the reasons are multiple. Here are the main reasons that will cause error code 3304:

Network instability: Any network problems can lead to the error code 3304 issue on Paramount Plus during playback, like a poor WIFI signal, packet loss, or limited bandwidth etc.

Ad blocker interruptions: Third-party plug-in units like AdBlock mistakenly recognize the player’s authentication script as an AD and block it, leading to the video not being played.

Corrupted browser caches: Over time, the piled-up caches may be hard to load and easily damaged, which can cause Paramount Plus to go wrong.

VPN or Proxy Interference: If you use VPN or proxies that are detected by Paramount Plus, there is a chance you will encounter error code 3304.

Hardware issues: Any hardware glitches can make the playback go wrong, such as hardware acceleration, outdated devices, etc.

How to Fix Paramount Plus Error Code 3304

Since we know the potential reasons, the most effective methods start with the likely culprits before moving to the complex hardware problems. You can follow the methods one by one to fix the problem.

1. Test Your Internet Connection

Error code 3304 usually fails the handshake between your device and Paramount Plus. Hence, the first step is to see if your internet connection runs uninterrupted. Go to speedtest.net to see if your bandwidth is limited. Often, the least requirement is 4 Mbps and 25 Mbps for 4K video. If your internet is too slow, consider to level up your bandwidth.

If the speed is normal, reboot your wifi network. Turn off your router and modem to let them refresh for a while. Additionally, using a wired cable is more stable for the connection. After 30 seconds, turn them on. Go to Paramount Plus to see if the problem is solved or not.

2. Disable Ad-Blockers and Privacy Extensions

AdBlock, uBLcok Origin, Privacy Badger, or some other third-party ad blockers can mistakenly recognize the program as intrusive content and block them so that the video cannot initialize. Try to disable these blockers to add the site paramountplus.com to the whitelist. Here are the steps.

Step 1: Click on the ad blocker icon on your browser’s upper right side.

Step 2: Click on the button that indicates to disable for the website.

Step 3: Close and reopen the browser and watch the video to see if the problem is resolved.

3. Turn Off VPN or Proxy Services

Some of the users like to use VPN or proxies because they need to access some foreign content. But, if you forget to turn it off, Paramount Plus may detect it and mark the connection as unsafe to cause error code 3304. Try to turn off the VPN and proxies to restore your genuine network identity to let the server verify your location.

Step 1: Open settings on your device (your phone, computer, or TV, etc.)

Step 2: Locate VPN.

Step 3: Disconnect VPN. (Note: if you use third-party VPN software, just go there to disconnect.)

4. Clear Browser Cache and Cookies

The accumulated caches and outdated cookies cannot match the connection process, which means the browser needs to use the outdated data or corrupted setups to load the video. Clearing this kind of data may help the browser request new data from the website, thus solving the error code 3304 problem.

Step 1: Click on the three dots in the upper-right corner of the browser.

Step 2: Choose Settings.

Step 3: Locate the Privacy and Security part.

Step 4: Click the button to clear the privacy data.

Step 5: Watch the video to see if the problem is resolved or not.

5. Disable Hardware Acceleration

The browser offloads certain tasks to the GPU to accelerate performance. If you turn on hardware acceleration may lead to video decoding and DRM conflicts, resulting in errors. Disabling the hardware acceleration forces the browser to use software decoding, which is more stable for streaming services.

Step 1: Click on the three dots in the right corner of the browser, then choose Settings.

Step 2: Search System in the address bar, or, in the left panel, locate the System tab.

Step 3: Toggle off the tab "Use graphics acceleration when available".

Step 4: Reboot the browser and watch the video to see if the problem is resolved.

6. Try Incognito Mode or a Different Browser

If you tried the above methods, but the error code still kept showing up, you can use the incognito mode to watch a video or just switch to another browser to test. The incognito mode can create a new environment that lets you access the website and doesn’t saving your data.

Step 1: Open the browser you use.

Step 2: Press Ctrl + Shift + N（Windows) to open an incognito window. You can also click on your profile > new incognito window.

Step 3: In this window, open Paramount Plus and try to play the video to see if the problem exists.

Step 4: If you fail to play, try using other browsers, such as Firefox or Safari.

7. Update or Reinstall the Paramount Plus App

If you stream Paramount Plus on mobile devices, smart TV, or game consoles, you can try to uninstall and reinstall the app. Reinstalling the app can clear the old data and replace the corrupted data with the newest version.

Step 1: Open the device’s settings (phone, TV, game console).

Step 2: Find applications and locate Paramount Plus.

Step 3: Tap the button the remove the app.

Step 4: Reboot the device.

Step 5: Go to the app store and search for Paramount Plus.

Step 6: In the detail page, tap on the install button.

Step 7: Watch the video to see if the problem still exists.

8. Power Cycle Your Devices

If none of the methods are working, but the problem is still there, maybe it’s a system glitch. Try rebooting the devices for a while (to clear the RAM) and reopening them to visit Paramount Plus. This method applies to any device, like a computer, phone, TV, or game console. However, if this method isn’t working, it may not be your side problem. Consider contacting the Paramount Plus support team to have targeted assistance.

Tips to Prevent Future Errors

To avoid any potential problems with Paramount Plus, I suggest downloading Paramount Plus videos offline to watch. Think about it, when you are ready for a trip, but the error code 3304 shows up, and you cannot fix it right away. At this time, you have downloaded videos as backup for your road trip, which makes things easier. However, Paramount Plus sets the DRM barriers. You cannot use the official app to download videos outside the app. Hence, the better option is to use a third-party video downloader.

Moreover, you can keep the downloads forever until you are tired of them. It’s easy to use, just copy and paste the video URL into the downloader and let it download for you.

Conclusion

I have tried all the methods above to fix error code 3304. Although they are effective, honestly, they are not always a permanent fix because streaming environment and server requirements keep changing, and there are always problems. So, besides learn the methods to fix the problem, it’s important to download videos offline in advance with software like Moyea Paramount Plus Downloader for your trip or planned watching party, also as a backup. Anyways, happy streaming!
