Steam Error Code 105 is a common network-related problem that prevents the Steam client from connecting to its servers. When this error occurs, users usually experience store pages not loading, login failures, or connection interruptions. The main cause behind Steam Error Code 105 is incorrect DNS settings, unstable internet connections, or corrupted network cache data. The good news is that this issue can usually be fixed with a few simple troubleshooting steps. This guide explains the most effective method to resolve Steam Error Code 105 and restore normal connectivity.
What Causes Steam Error Code 105?
Steam relies heavily on stable internet communication to function properly. When your system fails to resolve Steam server addresses correctly, you may see Error Code 105. This typically happens due to:
- Incorrect or slow DNS server settings
- Corrupted DNS cache files
- Network configuration conflicts
- Firewall or antivirus blocking Steam services
Fixing your DNS configuration and refreshing your network cache often resolves the issue.
Method 1: Change DNS Server Settings
Changing your DNS server is one of the most effective ways to fix Steam Error Code 105. Public DNS servers like Google DNS provide faster and more stable connections compared to many default ISP DNS servers.
First, open the Control Panel on your Windows computer. Inside Control Panel, click on Network and Internet. Next, select Network and Sharing Center, which displays your active network connection details.
On the left side, click Change adapter settings. You will now see a list of available network connections. Identify your active connection, which could be Wi-Fi or Ethernet depending on your setup. Right-click your active network connection and select Properties.
Inside the Properties window, scroll down and select Internet Protocol Version 4 (TCP/IPv4). After selecting it, click the Properties button. A new window will open where you can change IP and DNS settings.
Select the option Use the following DNS server addresses. Now enter the following values:
- Preferred DNS Server: 8.8.8.8
- Alternate DNS Server: 8.8.4.4
These DNS addresses belong to Google Public DNS, which is known for reliability and faster response times. After entering the values, click OK and close all network configuration windows.
Method 2: Flush DNS Cache Using Command Prompt
After updating your DNS settings, you should flush the DNS cache to remove outdated or corrupted records that may interfere with Steam connectivity.
Click the Start Menu and type CMD in the search bar. From the results, right-click Command Prompt and select Run as administrator. Administrative permission is required to perform network reset commands.
Once Command Prompt opens, type the following command carefully:
ipconfig /flushdns
Press Enter to execute the command. You should see a message confirming that the DNS Resolver Cache has been successfully flushed. This means your system has cleared old DNS records and will create fresh ones during future connections.
Final Step: Restart Your Computer
After completing the DNS configuration and flushing the DNS cache, restart your computer. Restarting ensures that all network changes apply correctly and establishes a fresh connection to Steam servers.
Once your PC restarts, launch Steam and check whether the error has been resolved. In most cases, Steam Error Code 105 disappears after performing these steps.
Additional Tips to Prevent Steam Error Code 105
If the problem continues, consider these additional solutions:
- Restart your router or modem
- Temporarily disable antivirus or firewall software
- Check Steam server status online
- Switch between Wi-Fi and Ethernet connection
- Ensure your Windows system is fully updated
Conclusion
Steam Error Code 105 mainly occurs due to DNS and network configuration problems that block Steam from communicating with its servers. By changing your DNS server to Google DNS, flushing your DNS cache, and restarting your system, you can usually fix this error quickly. Maintaining proper network settings and regularly updating your system can also help prevent similar Steam connectivity issues in the future.
