Several elements frequently cause this issue that making it difficult to pinpoint the exact cause. When you get this problem, you should first check to see whether the Hulu servers are down. If it’s a server issue, you’re probably not the only one who’s having a problem. Unfortunately, server issues are beyond the user’s control, and the only solution is to wait for Hulu to rectify the situation.  

Outdated browser repository 

As it turns out, this issue can also arise if your default browser’s repository has recently changed and the old version is no longer capable of supporting streaming protocols. All you have to do in this instance is update your browser to the most recent version available.

Even though Hulu promises to be compatible with most browsers, it is a good idea to use one that you are familiar with. Make sure you’re using the most recent version of your Browser because updates aren’t always notified, and most people are unaware that their Browser is out of date.

Corrupted cached data

Corrupted temporary files stored in your browser cache may cause the error code DRMCDM78 to appear unexpectedly, disrupting your streaming activity. You should be able to address the problem in this situation.   

TCP / IP Issue

The specific error code could occur for various reasons, including the Hulu server being down or undergoing maintenance, the Browser not being up to date, TCP/IP issues, browser cache, or cookies issues, and so on. So, to fix this problem we will go through all of the instructions listed below.

 Checking the Status of Hulu Servers 

To initiate the troubleshooting process first, ensure Hulu isn’t experiencing any server issues. So, before you do anything further, try services like IsItDownRightNow, Down Detector, or Outage Report to see if other users in your area have reported the same issue. You should also check the official Hulu Support account for any official announcements regarding the status of their streaming server if you’ve just discovered evidence that other customers around the world are reporting the same error.

If your examination revealed no underlying server issue, it’s safe to assume that this problem is only occurring locally due to a browser or network issue. In this article, you can find instructions for resolving these issues in different techniques.

Outdated Browser to the Latest Version

 If you’ve already looked into the problem and can’t find anything related to Hulu, it’s likely a browser issue. An outdated browser build is the most typical cause for the error code DRMCDM78 to appear.

Unless you upgrade to the most recent build available, your router has most certainly just deployed a repository modification that will cause certain streaming services to fail until you update to the most current version available. Of course, depending on the browser you’re using, this operation will be different.

If you’re using Chrome (on Windows, Mac OS X, or Linux), go to sub-guide A to force your browser to update to the most recent version. Any other Chromium-based browser is in the same boat (the steps are the same).

However, if you’re using Firefox (one of the few non-Chromium-based third-party browsers), follow sub-guide B to force it to update to the most recent version available.

Suppose none of the possible changes above have worked for you, and you’ve already validated that you’re not dealing with a server problem outside your control. In that case, you’re probably dealing with a TCP/IP discrepancy.

It is a common issue with low-level routers that can only handle a limited amount of bandwidth. When numerous devices are connected to the same network and trying to stream content from Hulu, this problem is more likely to occur.

You have two possibilities in this situation:

  • Restarting your router
  • Resetting your router

Although restarting is a non-intrusive method, it will only reveal problems involving temporarily stored data. You’ll need to reset your router if the problem is caused by a configuration or limitation placed at the router level.

Restarting your Router 

A fast reboot will fix the majority of any connectivity issues you may be experiencing. If the problem is connected to a TCP/IP issue, this should suffice.

To restart your router, glance at the back of the device and push the On-Off button to turn it off. Next, unplug the power cord from the outlet, and wait a full minute for the power capacitors to drain and any temp data that your router may be holding to be released.

Rebooting Router

After this time has moved, turn on your router and click the power button to restart it, then wait for Internet connectivity to return. Go for a router reset if the same problem is still happening.

Power Cycle your Router to Fix Hulu Error Code Drmcdm78

If the restart fails, you should proceed to the reset procedure. However, keep in mind that this operation will erase all of the settings you’ve made in your router’s settings. It covers, among other things, forwarded ports, whitelisted devices, and blocked connections.

If you’re aware of the risks but still want to restore your router’s factory settings, go ahead and locate the reset button on the back of your router. In most cases, it will be built inside the case to prevent accidental presses, so you’ll need a small screwdriver or a similar object to reach it.

Foresting the router, press and hold the reset button for 10 seconds or until all of the LEDs on the router flash simultaneously. If your Internet service provider (ISP) uses PPPoE (Point to Point Protocol over the Internet). In that case, you’ll need to re-enter the credentials provided by your ISP at the end of this procedure to regain Internet connection.
