Netflix Error M7034 on Windows

As it turns out, there are several different causes that might cause this problem:

  • Intrusive Browser Extension – As it turns out, there are several problematic browser extensions (including Malwarebytes extension) that might interfere with the streaming function of Netflix. In this case, you should be able to fix the issue by disabling this extension while using Netflix.
  • IP / TCP inconsistency – If a problematic extension is out of the question, you should turn your attention towards your router. A network inconsistency (bad gateway, restricted IP range) might end up triggering this error code. To fix it, try rebooting or resetting your router.
  • Bad cache data – Another potential culprit that might cause this error is badly cached data that your browser is currently holding on to. In this case, you will be able to fix the M7034 by clearing your browser’s cache.

Method 1: Disabling the Malwarebytes Extension (or similar)

As it turns out, one of the most common causes that will end up causing the Netflix Error M7034 is a browser extension that Netflix regards as intrusive – If this happens, Netflix app is build to stop any streaming attempts.

For example on Google Chrome, the most common culprit that might cause this error code is security extensions (most commonly Malwarebytes extension) and VPN clients enforced at a browser level.

If this scenario is applicable, you should be able to fix the issue by accessing your extension tab and disabling the problematic extension while using Netflix.

Here’s a quick guide that will show you how to do this on the most popular browsers (Chrome and Firefox):

A. Disabling Extensions on Chrome

  1. Open your Google Chrome browser and click on the action button (top-right section of the screen).
  2. From the newly appeared context menu, navigate to More Tools > Extensions and open the extensions tab of Google Chrome.

  3. Once you’re inside the Extensions menu, scroll down through the list of installed extensions and locate the AV / VPN extension that you think might be interfering with Netflix.
  4. When you find it, simply click on the toggle associated with the problematic extension to disable it.
    Disabling the extension
  5. After the extension has been disabled, restart your Chrome browser, then repeat the action that was previously causing the M7034 error.

B. Disabling Extensions (Add-ons) on Firefox

  1. Open Firefox and click on the action button in the top-right corner of the screen.
  2. From the next menu, click on Add-ons from the list of available options.
    Click on Add-ons options.
  3. Once you’re inside the Add-ons tab, click on Extensions from the left-hand side menu, then disable the toggle associate with the extension that you suspect might be interfering with the Netflix app.

  4. Restart your Firefox browser and repeat the streaming action on Netflix to see if the problem is now fixed.

In case you already disabled any problematic extensions that might end up causing this problem, move down to the next potential fix below.

Method 2: Reboot or Reset your Router

By far, the most common cause that will end up causing the M7034 error with Netflix is some type of network inconsistency (most commonly caused by a TCP / IP issue).

There are a lot of reports with affected users confirming that in their case, this error ended up occurring due to the fact that their network has become flooded with data – This is fairly common with networks where there are a lot of different devices connected to the same network.

If this scenario is applicable and you are using a router with a small usable bandwidth, follow the sub-guide below (A) to reset your router and see if this ends up fixing the issue. If that doesn’t work, move to the second sub-guide (B) to perform a complete router reset.

A. Performing a Router Reboot

  1. Look for the On/Off button on your router (typically located on the rear of the device).
  2. Press it once to turn your router off, then wait for a full minute.

  3. While you wait, physically disconnect the power cable from the power outlet it’s currently connected to in order to ensure that you also drain the power capacitors.
  4. Once this period passes, press the On/Off button again to start your router, then wait until the connection is re-established.
  5. When Internet access is restored, repeat the action that was previously causing the M7034 error and see if the problem is now fixed.

In case the issue persists, follow the sub-guide below to reset your router instead.

B. Performing a Router Reset

Note: Before initiating a router reset, keep in mind that this operation will end up clearing any personalized settings that you previously established, and depending on your router model, it might also clear any forwarded ports, custom credentials, whitelisted ports, blocked IPs, etc.

  1. Take a look at the rear of your router to find the reset button. It’s usually pushed a little inside so that there aren’t any accidental presses.
  2. When you find it, use a toothpick, screwdriver, or a similar object to press and hold the Reset button for 10 seconds or until you see that all the front LEDs flash at once.

  3. Once the reset procedure is successfully performed, re-establish the internet connection, and see if the Netflix error is now resolved.

In case the same problem is still occurring, move down to the next potential fix below.

Method 3: Clearing your Browser Cache

If none of the potential fixes above have worked for you, it’s possible that this issue is being caused by bad data that your browser is currently storing in the cache folder.

Some users that were also dealing with this problem have confirmed that the issue was finally resolved after they cleared the cookies & the cache folders of their browser.

If this scenario looks like it could be applicable, clear your browser cache and restart it before attempting to stream content from Netflix again.
