If you see the same error message repeating, move down to the next method below.

Method 2: Create Steam Network Shortcut with -nofriendsui parameter (PC Only)

Several users that were encountering this issue on Steam (PC ) have reported that the issue was fixed after they created a desktop shortcut of the steam game and used a series of launching parameters.

If you’re wondering what these parameters are doing – they will force the Steam client to use the old Friends UI and UDP/TCP protocol instead of the new WebSocket.

This supposedly circumvents an issue that Capcom has with their servers and might end up resolving the Error Code 50382 mw1. Here’s a quick guide on how you can create a desktop icon for Monster Hunter and add two nofriendsui parameters to it’s launching phase:

  1. Open steam, right-click on Monster Hunter: World and select Create Desktop Shortcut.
    Note: If you have not brought Monster Hunter: World through steam (you’re using a physical copy), skip this step altogether.
  2. Right-click on the desktop shortcut and choose Properties.
  3. Next, go to the Shortcut tab where we will start adding parameters to the Target entry. To do this, add ‘-nofriendsui -udp’ at the end of the Target field and click on Apply.

    Adding -nofriendsui -UDP or -nofriendsui -tcp parameters to Monster Hunter: World shortcut

  4. Launch Monster Hunter World via the shortcut that you’ve created and seen if the error has been resolved. If you’re still encountering the Error Code 50382 mw1 error, repeat step 3 again but this time add the ‘-nofriendsui -tcp’ parameter instead and hit Apply.
  5. Launch the game again and see if the modification is successful. If it isn’t, move down to the next method below.

Method 3: Changing the In-game matchmaking browsing ping to 250

Some users have successfully been able to resolve the problem indefinitely by modifying a built-in steam setting called In-Game server browser: Max Pings / minute. This can resolve the Error Code 50382 mw1 for those of you that are using an unstable internet connection that facilitates the apparition of networking problems when browsing various game servers.

Here’s a quick guide on changing the In-game matchmaking browsing ping to 250:

  1. Open steam and go to Steam > Settings (right-hand side) using the ribbon at the top."Steam
  2. Using the right pane of the Settings menu, choose In-Game.
  3. Next, go to the bottom where it says In-Game server browser: Max pings/minute and change the default settings (Automatic (5000) to 250.

  4. Click Ok to save the changes, then launch Monster Hunter: World again to see if you are able to join you friend’s session. If you’re still encountering the same issue, move down to the next method below.

Method 4: Forwarding some ports in your router

Capcom officially recommends that you forward some ports used by Monster Hunter: World if you’re experiencing connectivity issues or instability. Keep in mind that older routers were not designed to allow incoming network requests. Because of this, forwarding an incoming connection through the router to the game can make the network experience a lot better.

The exact steps of forwarding the required ports are highly dependent on your router model and manufacturer. However, you can follow this guide as a rough indicator on the steps that you need to take in order to get your Monster Hunter: World ports forwarded:

  1. First, you need to discover your router’s address. There are a couple of ways to do this, but let’s go for a method that is both free and easy. Pop open a Command Prompt window by pressing Windows key + R, type “cmd” and press Enter.
    Run dialog: cmd and press Ctrl + Shift + Enter
    Run dialog: cmd and press Enter
  2. Inside the Command Prompt, type “ipconfig” and hit Enter to get an Ethernet adapter overview. Next, scroll down to the Default Gateway of your connected internet network and copy it. This is your router address.
  3. Open your browser and insert the router IP address that you previously fetched in the address bar and press Enter.
    Acess your Router's settings
    Access your Router’s settings
  4. You will be prompted to insert your login credentials (username + passwords). If you haven’t changed those yourself, you might get lucky using default values like Username: admin and Password: admin or Username: admin and Password: 1234.
    Note: Your router model might have different default credentials. In this case, do an online search with the query ” *router model* + default login credentials” and you should be able to discover the default values.
  5. Next, you’ll need to discover the IP address of the computer or console that is running the game. On Windows, you can do this easily by following Step 1 and discovering the IP under IPv4 Adress. On Xbox One, you can find the IP address in Settings > Network > Advanced Settings. On PS4,  go to Settings > Network > View Connection Status.
    Finding computer’s IP address under IPv4 Address
  6. Now that you have the IP address of the device that is running Monster Hunter, return to your router settings and look for a Port Forwarding (or Forwarding) setting.

Next, open the connection ports required by Monster Hunter world. Here’s a list with ports used by the game according to various platforms:

PC

TCP: 27015-27030,27036-27037
UDP: 4380,27000-27031,27036

PlayStation 4

TCP: 1935,3478-3480
UDP: 3074,3478-3479

Xbox One

TCP: 3074
UDP: 88,500,3074,3544,4500

Save the changes in your router, then move to the device that is running the game, open Monster Hunter: World and see if the issue has been resolved.
