Some Hulu users are reporting that they regularly end up with the Hulu Error Code P-DEV320 when attempting to stream content from this service. In most cases, this error is reported to occur after dozens of minutes inside the show – If affected users attempt to resume playback after this error, they are met by the same error screen in just a couple of seconds.
We’ve investigated this particular issue thoroughly and it turns out that there are several different reasons why you might expect to see this particular error code. Here’s a shortlist of potential culprits:
- Hulu Server Outage – As it turns out, you can also expect to see this error code in situations where Hulu is in the middle of an outage period that affects user playback in your particular area. In this case, there is no fix that will magically fix the problem. The only thing you can do is confirm the issue and wait for the involved developers to fix the problem.
- TCP / IP Issue – Once you made sure that the issue is not being caused by a server issue, the next thing you should investigate is a network issue originating from your router cached data or settings. In this case, you should restart your router and consider resetting it if the problem is still occurring and you’re encountering a similar issue with other streaming clients.
- Corrupted Hulu Cookie / Cached data – If you’re only seeing this error when streaming TV shows from HULU on a PC (while playback on Smart TV or game console functions just fine), chances are you’re dealing with a cache issue. In this case, you can fix the problem simply by clearing your browser cookies and cached data.
- Conflicting data associated with your account – As some affected users have confirmed, this issue can also appear if Hulu is storing conflicting information related to your account. This might sometimes occur if you’re regularly switching between devices and playing content from the same account on multiple devices. In this case, you’ll need to open a ticket with Hulu’s support desk and ask them to reset your account data.
Method 1: Checking for Server Issues
Before you try any of the there fixes below, you should start by making sure that you’re not seeing this error code due to a server a widespread server issue that is entirely unfixable on your side.
As it’s happened in the past, you might see the Hulu Error Code P-DEV320 message if Hulu servers are currently unreachable by users in your area. If this scenario is applicable, you should start by following the official channels to verify whether there’s an issue with the main Hulu service.
There are multiple ways that will allow you to check on this, if you want the quickest router, use services like DownDetector or Outage.Report and see if other users living in your near vicinity are currently reporting the same issue.
If you notice that other users in your area are reporting the same problem, you should also check the official Twitter account of Hulu and check and see if there’s been an official announcement on the server issue.
In case the investigation you just did above didn’t reveal a server issue, chances are one of the methods below will fix the problem.
Note: If you just uncovered a server issue, none of the potential fixes below will work for you. In this case, all you can do is wait until the involved developers will fix the issue on their side.
So if there’s no evidence on a widespread server issue, move down to the next potential fix below.
Method 2: Restarting / Resetting your Router
In case you started by ensuring you’re not dealing with an inconsistency facilitated by a server issue, the next most likely culprit that you should investigate is your router. According to some affected users, a TCP or IP inconsistency can also be the main catalyst for this Hulu Error Code P-DEV320.
If this scenario looks like it could be applicable (especially if you are encountering similar issues with other services), you can most likely fix the issue in one of 2 ways:
- A. Restarting your router – This operation will refresh the current TCP and IP data that your router or modem is currently using without making any underlying changes that will affect future interactions. However, if this problem is being caused by a bad IP range, restarting your router will not guarantee that you will be granted a new IP range.
- B. Resetting your router – This is a more permanent type of fix that has the potential of clearing some of the lasting router settings that you’ve established previously. Once the reset procedure is complete, any whitelisted ports, blocked devices, and even saved PPPoE credentials will be cleared.
Ideally, you should start with a simple router reset and only go for the more permanent router reset procedure in case the issue persists.
A. Restarting your Router
If you want to avoid doing anything that will leave permanent marks, a simple restart is an ideal way to start. This will avoid the removal of sensitive data like PPPoE credentials, whitelisted ports, and blocked devices.
A simple restart will only clear the TCP (Transmission Control Protocol) and IP (Internet Protocol) temporary data of your current network connection without touching any sensitive data.
If the P-DEV320 error is occurring due to something rooted in your network temp files, this operation should fix the problem.
To perform a router reset, find the power (ON/OFF) button on your network device. When you find it, press it once to turn your router off, then wait for a full minute to ensure that the power capacitors are completely drained.
Note: While you wait, you should also disconnect the power cable from the power outlet it’s currently connected to.
Once the reset procedure is complete, reconnect the power cable and attempt to stream content from Hulu again to see if the problem is now fixed.
In case the same issue is still occurring, move down to the next potential fix below.
B. Resetting your Router
If a simple restart didn’t do the trick for you, you should move forward with a router reset to make sure a router setting is not actually causing the problem.
However, before you start this operation it’s important to ensure that you understand what this operation will do for you. If your ISP is using PPPoE (Point-to-Point Protocol over Ethernet), your credentials will be lost once the reset operation is complete – If this scenario is applicable, you should ensure that you have the credentials in hand before initiating this procedure (You’ll need them to re-established internet access).
Furthermore, a reset will also make you router ‘forget’ any whitelisted ports, blocked devices that are prevented from accessing the network, forwarded ports, etc.
Once you understand the consequences and you’re ready to initiate a reset procedure, start by looking for the reset button located on the back of your device.
To initiate a reset procedure, use a sharp object to press and hold on the reset button for about 10 seconds or until you notice all the front LEDs flashing at the same time – This is confirmation that the operation was performed successfully.
After the operation is complete, re-add the PPPoE credentials if needed to establish internet access and see if the problem is now fixed.
Method 3: Clear your Browser Cookies (if applicable)
If you’re facing this problem on a PC only when attempting to stream certain content from Hulu, you’re most likely dealing with a cache or cookie issue. Users that found themselves in the same situation have reported that they finally managed to fix the problem by clearing the cache and cookies related to Hulu.
However, depending on the browser that you’re using, the exact instructions for doing this will be different. Fortunately, you can make things easier for yourself by putting together a guide that will show you how to clear the cache & cookies on the most popular browsers (according to their market share).
Follow the dedicated instructions to clear the cookies and cache of your browser, then see if the problem is fixed.
In case you’re still stuck with the same Hulu Error Code P-DEV320 even after clearing the temp files related to your browser, move down to the next potential fix below.
Method 4: Contacting Hulu Support
In case you’ve followed every potential fix above and you’re still stuck with the same P-DEV320 error, your only choice by now is to get in contact with a Hulu support agent and ask them to investigate.
You can do this by opening a support ticket on their official support page.
Once you’re inside the support page, start by ensuring that you are signed in with the same Hulu account that you’re encountering streaming issues with.
After you’re finally allocated to a support agent, you will likely have to go through a series of pre-defined troubleshooting steps before the agent will finally reset your personalized data saved on their cloud service. Several affected users have reported that this was the only thing that allowed them to resume Hulu streaming without being interrupted by the same P-DEV320 error.
