How to Fix Netflix Error Code H7020?

The Netflix error code h7020 is typically encountered by Windows users that are trying to stream content using Internet Explorer 11 (or older). This particular error code indicates a server authentication issue. The problem is reported to occur on every recent Windows version (7, 8.1, and 10).

One of the most common causes that will cause this issue is a permission issue. So first things first, ensure that the IE program you’re using has administrator access before attempting to stream content from Netflix.

However, the problem can also be rooted in a security issue. It’s possible that Internet Explorer doesn’t recognize Netflix as a TLD (Top Level Domain), so it will block communications with it. In this case, you will need to add the root address of Netflix to the list of trusted websites.

Another potential cause that will spawn this error code h7020, is a feature called DOM storage. In case it’s disabled in your Internet Options, Netflix will be unable to stream content on your native browsers. In this case, you will need to enable it from the Advanced tab of Internet Options.

Running Internet Explorer as Administrator

As it turns out, the Netflix error code h7020 issue can very well be rooted in a permission issue. As it turns out, certain actions performed by the Netflix application will require administrative privileges, which Internet Explorer will not have by default.

In case this scenario is applicable, you should force the Internet Explorer program that you’re using to open with admin access.

To do this, press Windows key + R to open up a Run dialog box. Next, type ‘iexplore’ inside the text box and press Ctrl + Shift + Enter to open IE with admin access.

Opening IE with admin access

Note: When you’re prompted by the UAC (User Account Control), click Yes to grant administrative access.

After you successfully manage to open Internet Explorer with administrative access, attempt to use Netflix again and see if the issue is now resolved.

Adding Netflix as a Trusted Site

Keep in mind that Internet Explorer is quite rudimental and fixed when referring to its security rules. As opposed to every other browser, it doesn’t know to distinguish between trusted TLDs and regular domains.

Because of this, one of the reasons that might spawn the error code h7020 is a trust issue between Netflix and Internet Explorer.

If this scenario is applicable, you can fix the problem by accessing the Settings menu of Internet Explorer and adding Netflix to the list of trusted websites.

Here’s a quick guide on how you can do this:

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘inetcpl.cpl’ inside the text box and press Enter to open up the Internet Properties screen.

DOM Storage is an industry-standard already, but if you are using an outdated IE browser, this might be disabled by default.

If you think this scenario might be applicable, follow the instructions below to enable DOM Storage in Internet Explorer:

  1. Open Internet Explorer and click on the gear icon (top-right corner).
  2. Next, click on Internet Options from the newly appeared context menu.
  3. Inside Internet Options, select the Advanced tab, then scroll down to Security (under Settings), and make sure that the checkbox associated with Enable DOM Storage is enabled.
