Why Can’t I Connect to My Valheim Server?

Struggling to join your Valheim server and eager to get back to building, exploring, and battling the creatures of the tenth Norse world? It’s a frustrating situation, but one that many players encounter. The issue is rarely straightforward, with a variety of potential culprits ranging from simple user errors to complex network configurations. In short, you’re likely unable to connect to your Valheim server due to firewall restrictions, incorrect server settings, outdated game files, port issues, server overload, or simply the server being offline. Let’s delve into each of these reasons in detail and explore the fixes you can implement to get you back into the Viking action.

Common Connection Problems and Solutions

Firewall Interference

Your firewall acts as a security gate, monitoring incoming and outgoing network traffic. If not configured correctly, it can block Valheim’s attempts to connect to a server. To troubleshoot this, first, try temporarily disabling your firewall (often found in Windows Settings > Update & Security > Firewall & network protection). If this allows you to connect, you know the firewall is the culprit. You’ll then need to create exceptions or “inbound rules” in your firewall settings to allow Valheim through. This usually involves permitting both TCP and UDP traffic on specific ports (usually 2456-2458 for UDP). Refer to the detailed instructions below (in the FAQs section) to precisely configure your firewall for Valheim. Remember to enable your firewall after testing.

Incorrect Server IP Address or Port

One of the most common issues is simply entering the wrong server IP address or port number. Valheim requires the correct IP address and port to establish a connection. If you’re using a port that ends in “1” make sure to use the one ending in “0” instead (e.g., 28001 becomes 28000). You can find the correct IP address in your server’s Settings or Status section. Ensure you’re entering the exact address without any typos and using the correct port. Pay close attention to this detail, as a single incorrect digit can prevent a connection.

Game File Corruption or Missing Files

Sometimes, your Valheim game files can become corrupted or partially missing, leading to connection problems. To fix this, verify the integrity of your game files through Steam. This process will check your game files and redownload any that are missing or damaged. To do this, go to your Steam Library, right-click Valheim, select Properties, go to the Local Files tab, and click Verify integrity of game files. This can often resolve issues stemming from faulty or missing game data.

Server Port Issues

Valheim relies on specific ports to communicate with servers. If these ports are blocked by your router or firewall, you will be unable to connect. You’ll need to ensure that the relevant ports (listed below in the FAQs) are forwarded on your router and that your firewall is set up to allow the correct inbound and outbound traffic. If you’re not familiar with port forwarding, you may need to refer to your router’s manual or seek assistance from someone with networking knowledge. If your server is hosted externally, you may have to contact your server provider to ensure that the required ports are open on their end.

Outdated Game or Server Version

An incompatibility between the server and client game versions can also prevent connection. Make sure both your game and the server are running the same Valheim version. This usually means that you must update Valheim to the latest version, and you’ll also need to check with the server host to ensure that the server is updated too. If your game version and the server version do not match, you will be unable to connect.

Server Overload or Downtime

If the Valheim server is overloaded with players or experiencing downtime, you may not be able to connect. This often happens with popular servers, where the server hardware may be struggling to handle all of the players connecting at once. If the server is overloaded, you may just need to wait until some players disconnect before trying again. Always check the Valheim community forums or server host websites to see if there are any known server issues or maintenance taking place.

Unstable Internet Connection

A poor or unstable internet connection can cause connection issues. Check your internet speed and stability to ensure your connection is working correctly and is not experiencing any issues. You could try testing your internet speed with an online speed testing tool to ensure that it’s meeting the minimum requirement. If your internet connection is unstable, you may need to contact your internet service provider for assistance.

Can I use a “Join code” to connect?

Yes, Valheim allows you to join via an invitation code. When hosting a server through the game, or a dedicated server, a join code can be obtained through the pause menu. Your friends can then input this code through the “Add Server” button in the “Join Game” menu.

Why do I keep getting disconnected from Valheim?

Disconnects are usually caused by corrupt game files, server issues, unstable internet connection, or outdated game versions. Ensure your files are verified, server is stable, and your internet is strong.

How much RAM does a Valheim server need?

A Valheim dedicated server needs at least 3GB of RAM for relatively small worlds with few players. More RAM may be required for larger player counts and more extensive worlds.

Can I leave my Valheim server running 24/7?

Yes, you can have a Valheim server running 24/7 using the “Valheim Dedicated Server” tool. This allows others to play even when you are not online.

How much bandwidth does Valheim need?

For a 10-player server, you should aim for at least 500 Mbps of bandwidth. However, even with lower bandwidth, you may still be able to play with fewer players.

What is the data limit for Valheim?

Valheim has a default network transmission limit of 50kbps. This will not usually impact gameplay, but is good to be aware of.

How do I improve my Valheim connection?

To improve your connection, ensure you’re using suitable hardware, avoid playing on overloaded servers, close any other apps using up bandwidth, and use a dedicated server. Also, check your internet connection stability.

Is Valheim an offline game?

Yes, Valheim allows offline play to explore worlds you’ve already created, but you need to be online to join or host servers with others.

Can my friend play on my Valheim server without me?

Yes, with a dedicated server, your friends can play even when you are not online, as long as the server application is running.

How safe is port forwarding?

Port forwarding can present a security risk if not configured correctly. Ensure your firewall is set up properly, and ideally have a strong understanding of network configuration to ensure that no unwanted users can connect.

Can I use cheats on a dedicated Valheim server?

Yes, but only if you are the server host. To enable cheats, you must first start the server world in single player, use the console to enable the cheats, then exit and reload the dedicated server.

By meticulously addressing each of these potential causes, you will significantly increase your chances of successfully connecting to your Valheim server and getting back to the game. Happy adventuring!
