On the other hand, if this investigation didn’t allow you to discover any server issues, move down to the first fix below that will show you how to fix the RUNUNK13 error is originating from a local problem.

Method 2: Refreshing your Network

If you recently made sure that the problem is not due to server related, the first thing you should troubleshoot against is a network-related inconsistency caused by your router or modem. As some affected users have confirmed, this RUNUNK13 issue can also be caused by a TCP or IP inconsistency.

In this case, you have 2 ways of fixing the problem:

  • Restarting your network device – This operation will only refresh your current IP and TCP data that your router or modem maintains without making any underlying changes that will affect other components of your network. However, this operation will only fix problems caused by TCP and IP cached data – If the issue is being caused by a ‘set-in-sone’ setting, this method will be ineffective.
  • Resetting your network device – This is much more effective than just a simple restart since it will also clear any custom settings in addition to clearing your cached data. However, the main disadvantage of using this method is that you’ll lose any currently whitelisted ports, blocked devices, and saved PPPoE credentials – Your router will return to its factory state.

A. Restarting your Network Device

In case you want to start simple without running the risk of reverting some custom settings that you might depend on, a simple router restart is ideal since it will only clear the cached data related to Transmission Control Protocol and the Internet Protocol.

To perform a reset on your network device, look at the rear of your router or modem, and find the ON / OFF button. When you find it, press it once to turn your router off, then disconnect the power cable of your router/modem in order to give the power capacitors enough time to discharge.

Rebooting Router

Note: After you disconnect the power cable, wait for a full minute before plugging it back in and starting it once again.

Once internet access is restored, initiate another streaming job inside Hulu and see if the problem is now fixed.

B. Resetting your Network Device

If a simple reset didn’t fix the problem for you, or you’re looking for something that will revert your router settings, you should go for the reset procedure.

However, it’s important to understand that this operation will essentially revert any custom settings saved by your router or modem back to their factory defaults. This will not big a big issue unless you previously enforced whitelisted ports, blocked devices, or did some manual forwarding from your router settings.

Note: If your ISP is using PPPoE, resetting your router will mean that your network device will ‘forget’ the login credentials.

To initiate a router reset, look to the rear of your router for the reset button – It’s typically built-into the device, you’ll need a sharp object to reach it.

Once you manage to locate the reset button, press and hold it for about 10 seconds or until you see the front LEDs flashing at the same time. After you notice this behavior, release the reset button and re-establish internet access by reinserting your PPPoE credentials (If necessary) before initiating another streaming job in Hulu.

If this problem is still not fixed, move down to the next potential fix below.

Method 3: Clearing your Browser Cache
