Fix Steam Error Code 105 Unable To Connect To Server (2025)

Updated: 11/29/2025

You open Steam, click on the Store or Community tab, and instead of content you see Error Code 105 with a message about being unable to connect to the server. Your friends list may still work and online games may play fine, which makes the store error puzzling. This code usually points to DNS or proxy problems, browser like cache issues inside Steam, or security tools blocking the web content layer.

Method 1: Disable Proxies, VPNs, And Conflicting DNS Settings

Open your network adapter’s IPv4 settings and set DNS to trusted servers such as 8.8.8.8 and 8.8.4.4, then click OK to save. After changing DNS, fully restart Steam and test the Store and Community pages again.

Method 2: Flush DNS Cache And Reset Network Stack

Restart your computer so the changes are applied, then power cycle your router by unplugging it for 20 seconds and plugging it back in. When your internet is restored, launch Steam and open the Store page to verify whether Error 105 is resolved.

Warning: On corporate or campus networks, network and DNS changes may be controlled centrally, always verify policies before altering them.

Method 3: Clear Steam Web Browser Cache And Adjust Security Software

As a final network check, connect your PC to a mobile hotspot and open Steam. If Error 105 disappears on the alternate connection, your original ISP or router is likely interfering with content delivery, and you may need to adjust router DNS or firewall settings accordingly.
