Steam Error Code 105

Steam has become the go-to platform for PC gamers worldwide, offering a vast library of games and a robust community. However, like any online service, it can encounter issues. One such problem is Steam Error Code 105, which can prevent users from accessing their games and the Steam store. This comprehensive guide will walk you through understanding, troubleshooting, and resolving this frustrating error.

Understanding Steam Error Code 105

Steam Error Code 105

Steam Error Code 105 is a connectivity issue that occurs when the Steam client fails to establish a connection with its servers. This error can be particularly frustrating for gamers eager to dive into their favorite titles or browse the latest releases on the Steam store.

Symptoms and Impact

When encountering Error Code 105, users typically experience:

  • Inability to access the Steam store
  • Problems connecting to community features
  • Difficulty launching games from their library
  • Error messages suggesting server unavailability or internet connection issues

The impact of this error extends beyond mere inconvenience. It effectively locks users out of the Steam ecosystem, preventing them from purchasing new games, engaging with community features, and even accessing their existing game library. For many, this can disrupt planned gaming sessions and lead to significant frustration.

Common Causes of Steam Error Code 105

Understanding the root causes of Error Code 105 is crucial for effective troubleshooting. Here are the primary factors that can trigger this issue:

1. DNS Resolution Issues

DNS (Domain Name System) problems are a frequent culprit behind Error Code 105. When your computer fails to translate Steam’s domain names into IP addresses, it cannot connect to the necessary servers.

2. Server Downtime

Occasionally, Steam’s servers may undergo maintenance or experience outages due to high traffic or technical issues. During these periods, users may encounter Error Code 105.

3. Internet Connectivity Problems

A slow or unstable internet connection can disrupt communication between your device and Steam’s servers, leading to Error Code 105.

4. Firewall and Antivirus Interference

Overzealous security software can sometimes mistake Steam’s network activity for a threat and block its connection attempts.

5. Ad Blocker Conflicts

Certain ad-blocking software or browser extensions can interfere with Steam’s ability to connect to its servers.

Basic Troubleshooting Steps

Before diving into more advanced solutions, it’s essential to start with some basic troubleshooting steps:

1. Check Your Internet Connection

Ensure that your internet connection is stable and functioning correctly. Try accessing other websites or online services to verify connectivity.

2. Verify Steam Server Status

Visit the Steam Status page or check Downdetector to see if there are any reported server issues. If Steam’s servers are down, you’ll need to wait until they’re back online.

3. Restart Your Router and Computer

Restarting the Internet Router

Sometimes, a simple restart can resolve connectivity issues:

  1. Turn off your computer and unplug your router.
  2. Wait for about 30 seconds.
  3. Plug the router back in and wait for it to fully restart.
  4. Turn on your computer and try connecting to Steam again.

4. Disable VPN or Proxy Services

If you’re using a VPN or proxy service, try disabling it temporarily. These services can sometimes interfere with Steam’s connection.

Advanced Fixes for Steam Error Code 105

If the basic steps don’t resolve the issue, try these more advanced solutions:

1. Flush DNS Cache

Clearing your DNS cache can often resolve connectivity issues:

ipconfig/flushdns
  1. Press Windows + R to open the Run dialog.
  2. Type cmd and press Enter to open Command Prompt.
  3. Enter the following command: ipconfig /flushdns
  4. Press Enter and wait for the confirmation message.

2. Change DNS Servers

Switching to a public DNS server can improve connectivity:

  1. Open your Network & Internet settings.
  2. Click on “Change adapter options.”
  3. Right-click on your active network connection and select “Properties.”
  4. Select “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties.”
  5. Choose “Use the following DNS server addresses.”
  6. Enter 8.8.8.8 for the Preferred DNS server and 8.8.4.4 for the Alternate DNS server (Google’s public DNS).
  7. Click OK to save changes.

3. Configure Firewall Settings

Ensure that Steam is allowed through your firewall:

  1. Open Windows Defender Firewall settings.
  2. Click on “Allow an app or feature through Windows Defender Firewall.”
  3. Locate Steam in the list and ensure it’s checked for both private and public networks.
  4. If Steam isn’t listed, click “Allow another app” and browse to the Steam installation folder to add it.

4. Update Network Drivers

Outdated network drivers can cause connectivity issues:

  1. Open Device Manager.
  2. Expand the “Network adapters” section.
  3. Right-click on your network adapter and select “Update driver.”
  4. Choose “Search automatically for updated driver software.”

5. Set Up Port Forwarding for Steam

Configuring port forwarding can help Steam connect to its servers:

  1. Access your router’s configuration page (usually by entering 192.168.1.1 in your browser).
  2. Locate the port forwarding section.
  3. Add a new rule for Steam, forwarding the following ports:
    • UDP: 27000-27100
    • TCP: 27015-27030
  4. Save the changes and restart your router.

Addressing Software Conflicts

Sometimes, other software on your system can interfere with Steam’s connectivity:

1. Disable Ad Blockers Temporarily

Disable the add-on of ad blocker

Ad blockers can sometimes interfere with Steam’s connection:

  1. Locate your ad blocker extension in your browser.
  2. Disable it temporarily and try connecting to Steam again.
  3. If successful, consider adding Steam to your ad blocker’s whitelist.

2. Adjust Antivirus Settings

Your antivirus software might be blocking Steam:

  1. Open your antivirus program.
  2. Look for application control or firewall settings.
  3. Add Steam to the list of trusted applications.

3. Check for Conflicting Applications

Other applications might be interfering with Steam:

  1. Perform a clean boot to start Windows with a minimal set of drivers and startup programs.
  2. If Steam works in clean boot mode, gradually re-enable startup items and services to identify the conflict.

Network and Router Configurations

Sometimes, the issue lies with your network setup:

1. Review Router Settings

Ensure your router isn’t blocking Steam:

  1. Access your router’s admin page.
  2. Check for any settings that might be restricting outbound connections.
  3. Look for options like “Application Layer Gateway” or “SPI Firewall” and disable them if present.

2. Disable IPv6 If Necessary

Some users report that disabling IPv6 can resolve connectivity issues:

  1. Open Network & Internet settings.
  2. Click on “Change adapter options.”
  3. Right-click on your active connection and select “Properties.”
  4. Uncheck “Internet Protocol Version 6 (TCP/IPv6).”
  5. Click OK to save changes.

3. Set Up Quality of Service (QoS) for Steam

Prioritizing Steam traffic can help:

  1. Access your router’s QoS settings.
  2. Add a rule to prioritize traffic for Steam’s ports (mentioned in the port forwarding section).
  3. Save changes and restart your router.
