How to Fix Hulu Error Code P-DEV320 [Fixed]

Hulu is a really popular streaming platform that contains a huge userbase and is primarily famous due to its large collection of amazing Movies and TV shows. However, in recent events, we have seen that some users have been getting the Hulu Error Code P-DEV320 message on their devices which is preventing them from being able to stream properly.

What Causes the Hulu Error Code P-DEV 320?

After some intense investigation of this matter, we decided that the reasons listed below are the main triggers behind this issue.

• Cache and Cookies: In some cases, the cache or the cookies being stored on the devices might actually be preventing the network connection from being established between your Streaming device and Hulu servers due to which this error is being triggered.
• Account Glitch: It is also possible that the Hulu Account with which you are trying to stream is triggering the Hulu Error Code P-DEV320 because it hasn’t been signed in properly. It is recommended that you toggle the sign-in process one time to ensure that it is not the case.
• Outdated Software: It is also a possibility that the software being used on the streaming device might be preventing you from being able to properly stream. Therefore, it is recommended that you try and update this software.

Now that you are familiar with most of the reasons behind the occurrence of this particular issue, we will be moving on towards actually fixing it.

Before you start:

1. Take the power adapter of your router out of the socket and wait for it to shut down.

   

2. After waiting for a couple of minutes, power cycle the router by inserting its power adapters into the socket and wait for it to start.
3. When the router acquires full signal strength, launch your favorite browser and run an internet speed test. The recommended speed to run a smooth stream is indexed below.

   3.0 Mbps for TV shows and movies
   8.0 Mbps for live streams
   16.0 Mbps for all 4K content

4. If the error still persists, connect your console directly to the router with the help of an Ethernet cable, and switch to a wired connection.

   

5. Sometimes, this error might occur if the Hulu servers are under maintenance, If this is the case, then the solution is beyond your control. You can check the server status by visiting the Down detector website and if the servers are down, the only thing you can do is to patiently wait for them to start working.
