 MONSTER HUNTER: WORLD Server Connection Issues

  • 83-MW1 Error Code Fix

The solution to the 83-MW1 error code comes courtesy of Steam user, Forever_Lona. The fix – which may or may not work for all players – involves changing some settings in Steam and adding a few works to the Monster Hunter: World launch properties. As stated, though lots of users have found this to fix their problem, it is in no way guaranteed to solve all players’ problems.

  1. Open Steam
  2. Click Steam in the top left corner
  3. Select Settings
  4. Select In-Game
  5. Uncheck the middle box which states: Use the Big Picture Overlay when using a Steam Input enabled controller from the desktop

This will disable Steam’s Big Picture Overlay when using a controller while on PC and replace it with the standard Steam user interface. Next players will need to write two lines of code into the Monster Hunter: World launch options.

  1. Open Steam game library
  2. Right-click Monster Hunter: World
  3. Select Properties
  4. Click Set Launch Options…
  5. In the dialogue box, input the following, including the dashes and the space between the words: -nofriendsui -udp
  6. Click Okay
  7. Restart Steam

These two “codes” tells Monster Hunter: World how to launch. The first string tells the game not to start the new friends user interface when the game launches and the second string has to do with the various internet protocols.

Hopefully you’ll never see the 83-MW1 error code again and that this has an immediate positive effect on your ability to stay connected to the online server in Monster Hunter: World. In the event this does not fix the disconnect error, it could be worth trying to forward the Monster Hunter: World and Steam ports in your router/modem, doing a hard internet reset, connect to the router using a physical connection, or restarting everything.

  • Another solution to fix your connection issue is port forwarding:

Open the following ports on your router/firewall. Worked for some players.

TCP: 27015-27030 / 27036-27037

UDP: 4380 / 27000-27031 / 27036

  • NP-31980-1 Monster Hunter World Error

Let’s explain the NP-31980-1 Monster Hunter World error first. Basically, the problem is very simple and equally easy to fix. This error code is given mostly while trying to join a quest and the room is completely full with no way to get in. Of course, when you first try to join a quest, it may look like there is a spot open, but this error is given if someone happens to join right before you do.

The NP-31980-1 Monster Hunter World error is simple enough to fix because of its easy cause. If you are joining a quest that is quite popular like a Tempered one, then it is possible that someone might beat you to joining the quest. Because of this, there are a couple of things you can do.

The first way of fixing (or preventing) this NP-31980-1 Monster Hunter World error is contacting someone and making a private quest with a password so others can’t join before you. Another way of fixing this is simply being patient and waiting for another. If you don’t want to wait, we recommend being the host for the quest(s) you’re looking to do.

Until now these are the fixes that worked for us. We are constantly updating the article with more workarounds so make sure to check it out if you are experiencing new issues. Also, if there are any errors that we didn’t talk about please comment below and we will help you fix your game.

    I’ve done both, still have the problem.

    The only other time I had a connection problem was from dragon’s dogma.
