What Causes the Monster Hunter World Error Code 5038f MW1?

The error is often caused by incompatibilities with your router which often accidentally blocks your console from connecting to the Internet properly. This can only be solved by assigning a static IP for your console and placing its IP in the DMZ (Demilitarized Zone).

PC users who own the game on Steam can try disabling the Steam Overlay as it helped plenty of people.

Solution for Console Users: Add Your Console to the DMZ in Your Router

Playing online games with your console can be quite tricky as the console’s IP can keep changing from time to time. After fixing its IP, you will have to add it to DMZ (De-Militarized Zone) where it should be safe without connection issues.

First up is finding out the IP of your respective consoles:

PlayStation 4 Users:

  1. In the PlayStation 4 main menu select Settings >> Network >> View Connection Status.
View Connection Status

  1. Locate the IP address in the screen which opens up and make sure you write it down somewhere since you will need it to enable port forwarding. Make sure you also write down the MAC address of your PS4.

Xbox One Users:

  1. Navigate to the home screen and push the menu button on the controller of your Xbox one.
  2. Navigate to Settings >> Network >> Advanced Settings.

  1. In the IP settings section you should see the IP address listed. Write down this number because you will need to assign the IP address later.
  2. You should see Wired MAC address or Wireless MAC address listed under IP settings as well. Write down the 12-digit address for the connection that you are using.

Now we will need to assign static IP addresses to the consoles by following the steps below:

  1. Open a Web browser, type your Default Gateway number (IP address) into the address bar, and press Enter.
  2. Enter your username and password to access your router’s interface. The default username and password should be listed in your router’s documentation, on a sticker on the side of your router, or on the Port Forward website.

  2. Locate the window which allows you to type in the MAC address and the IP address of your choice so type in the addresses which you have gathered in the previous steps for your respective console.

Now, we’ll need to add your console’s IP address to the DMZ which is a setting located in the menu after you login into your router using an Internet browser from a device connected to it.

  1. Open a Web browser, type your Default Gateway number (IP address) into the address bar, and press Enter. Make sure you login the same way as above!

  1. Locate the DMZ option in the Settings tab of your router. The option is always in a different location but it will most likely show up under the Security tab or something similar.
  2. Choose the DMZ option and enter the static IP address you assigned to your console. If everything goes right, your console should now have access to the Internet. After you have confirmed these changes, make sure you turn off your router and your console and wait for a couple of minutes.

  1. Turn the console on, launch Monster Hunter and check to see if the error code still appears.

Solution for Steam Users: Disable Steam Overlay and Other Settings for the Game

  1. Open up Steam on your computer by double-clicking its entry on the Desktop or by searching for it in the Start menu.

  1. Navigate to the Library tab in the Steam window by locating the Library tab at the top of the window, and locate Monster Hunter in the list of games you have in your respective library.
  2. Right-click on the game’s icon in the list and choose the Properties option from the context menu which will show up. Click the Set launch options button.

  1. Type “-nofriendsui –udp –nofriendsui -tcp” in the bar. If there were some other launch options located there you are possibly using, make sure you separate this one with a space. Click the Ok button in order to confirm the changes.
