Disney-owned streaming service, Hulu, is one of the biggest competitors of Netflix. Though it might not compare to Netflix when it comes to paid subscribers, which sits around 35.5 million as of the third quarter of 2020, it has its own share of loyal subscribers.

Just like other streaming apps, Hulu is very easy to use and is compatible with most streaming devices, including Android phones and tablets, select models of Android TV, Apple TV, Chromecast, Fire TV and Fire TV Stick, iPhones and iPads, Nintendo Switch, Mac and PC browsers/apps, PS3 and PS4, Roku and Roku Stick, Xbox 360 and Xbox One, and Samsung TV.

However, encountering an error while streaming often ruins the experience. Instead of enjoying uninterrupted movies and TV shows, an error message pops up and prevents you from enjoying what you are watching. In some cases, even the entire app freezes or completely crashes due to Hulu errors.

One of the commonly encountered streaming errors is the Hulu error code DRMCDM78. This annoying error can pop up randomly and prevents you from streaming the video that you have selected. According to user discussions in the various forums, this error is widespread and often goes unresolved for a couple of days.

The error often affects any content on Hulu, which means that the problem is not specific to a particular type of content or channel.

What Causes Hulu Error Code DRMCDM78?

This problem is usually caused by several factors and it is hard to pin down the actual culprit. When this error appears, the first thing you need to ask is whether the Hulu servers are down. If a server issue is causing the problem, then you’re probably not the only one affected. Unfortunately, server problems are beyond the user’s control and there is no fix except to wait for Hulu to resolve the problem themselves.

If you’re using a browser to stream Hulu when this error happens, it is possible that the browser you are using is either not compatible with Hulu or is outdated. Though Hulu claims that it is compatible with most browsers, it is a good idea to use one that you trust. Make sure you’re using the latest version of the browser because sometimes these updates are not announced, so most users are not even aware that their browser is already outdated.

A corrupted and outdated cache may also trigger the Hulu error code DRMCDM78. Corrupted temporary files stored on your browser cache might interfere with your streaming activities, causing the error code DRMCDM78 to suddenly appear.

In some cases, the DRMCDM78 happens because of an inconsistency with your computer’s TCP or IP values. This means that there is some issue with your internet connection that is preventing Hulu from fetching the content from the servers, resulting in the Hulu error code DRMCDM78.

This list is not actually complete because there are other unknown factors that might trigger this error. But most reports cite either one or a combination of the factors above as the reason behind the appearance of error code DRMCDM78.

How to Fix Error Code DRMCDM78 Hulu

Since this error code can be triggered by a multitude of factors, which only a few we only know of, it is important to start from the basic troubleshooting down to the specific solutions. To start with, here are some basic housekeeping that might help resolve this error:

  • Restart your streaming device. If you’re using a computer, close the browser, reboot the computer, then unplug, if applicable. Turn it back on after a minute to check if the error has gone away.
  • Switch to a different network. Use a cable to connect to the internet if possible. If not, find an area with a better signal and stream from there. It might be a little uncomfortable, but at least you won’t be dealing with error code DRMCDM78 anymore.
  • Scan for malware to make sure it is not being caused by cybercriminals.
  • Log out, then log back into your Hulu account. Open your browser then go to the Hulu website to sign out of your account. Sign back in and check if it made any difference.

If none of the basic troubleshooting steps worked, proceed with the solutions below:

Fix #1: Check the Status of the Hulu Servers.

Make sure that Hulu isn’t currently experiencing some type of server issue when the error happens because if that is the case, the problem will be out of your control and you can only wait for Hulu to sort it out. You can use downtime checkers, such as IsItDownRightNow, Outage Report, or Down Detector to find out whether other users in your area are experiencing the same problem. If Hulu servers are indeed down, then wait for the official announcement from Hulu about the issue and when they expect it to be resolved.

Fix #2: Update Your Browser.

  • Mozilla Firefox – Go to Menu > Help > About Firefox to initiate an automatic update.
  • MS Edge (Chromium) – Navigate to Menu > Help and feedback > About Microsoft Edge to update the browser.
