Steam Error 105 appears when the client cannot connect to Steam's content servers or store backend. It overlaps with scheduled maintenance and local network misconfiguration. Check Steam status before reinstalling.

Maintenance vs local network
Valve maintenance commonly triggers 105 for store browsing while downloads may continue. If status is operational, focus on DNS, firewall, and proxy settings.
Windows, macOS, and Steam Deck
Windows: flush DNS and exclude Steam folder from antivirus. macOS: check proxy settings in System Settings. Steam Deck: verify Wi‑Fi and restart Steam in Gaming mode — Error 105 on Deck often follows DNS issues on public networks.
How to fix step by step
- 1Check live Steam server status on Oracnoos.
- 2Restart the Steam client completely — exit from the system tray too.
- 3Flush DNS: ipconfig /flushdns on Windows or equivalent on macOS.
- 4Disable VPN, proxy, and third-party firewall temporarily.
- 5Change DNS to 1.1.1.1 or 8.8.8.8 and reboot your router.
- 6Verify Steam servers on store.steampowered.com in a browser.
- 7If errors persist after status recovery, verify game files or reinstall Steam as last resort.
