Steam Error Code 105 is a pervasive network failure that cuts off the desktop client application from loading community pages, store tabs, or starting digital matches. This error signals that the Steam client’s built-in web browser component has failed to resolve the domain name system addresses for Valve’s data networks, leaving users stranded on a blank error screen.
Whether this connectivity block is caused by stale browser cookie directories inside the application files or conflicting local internet security configurations, you can clear it. Follow this step-by-step troubleshooting guide to bypass error 105 and reconnect your gaming library.
Common Causes of Error Code 105
• Stale Built-In Browser Cache: Fragmented temporary app files blocking the server manifest request pipelines.
• DNS Resolution Failure: Your internet provider’s default network routing tables failing to connect with Steam distribution servers.
• Ad-Blocker and Proxy Conflicts: Local tracking protections or proxy setups mistaking regular app handshakes for malicious requests.
Method 1: Purge the Steam Client Internal Web Browser Cache
Leftover web data blocks inside the client can easily distort secure internet handshakes. Wiping this specific internal partition forces the client to build completely clean connections.
- Open the Steam desktop application and click on Steam in the top left corner of the interface.
- Select Settings from the drop-down menu window overlay choices.
- Navigate to the In Game tab located on the left sidebar tree layout.
- Find the option labeled Delete Web Browser Data and click the corresponding delete button.
- Click Confirm on the pop-up box, restart the Steam client entirely, and attempt to access the store.
Method 2: Flush the Windows DNS Cache and Renew Your IP Address
If your local operating system network tables become crowded or out of sync, forcing an administrative network refresh will clear out communication bottlenecks instantly.
- Click your Windows Start menu icon, type CMD, right-click Command Prompt, and choose Run as Administrator.
- Type the following command exactly as written to clear old network maps and hit Enter:
ipconfig /flushdns - Once successful, type this command to release your old IP assignment and hit Enter:
ipconfig /release - Finally, type this command to secure a fresh, unblocked network address and hit Enter:
ipconfig /renew - Close the console window and launch your game client to verify the connection.
