How to Fix Steam Error Code 50 on Windows (2026 Guide)

How to Fix Steam Error Code 50 on Windows

Steam Error Code 50 typically occurs due to a timeout connection error, often interrupting purchases or library synchronization. It is frustrating, but usually fixable without reinstalling the entire client.

Before we start deleting files or running commands, let’s try the "Session Reset" trick. This often clears server-side glitches.

1. Go to Steam > Settings > Security > Manage Steam Guard.
2. Click "Deauthorize all other devices" (or Sign out of all other devices).
3. Restart Steam and try logging in again.

If that didn't work, follow these technical fixes to get your account back in order.

Method 1: Clear Steam Temporary Files

Corrupted temporary data in your Windows user folder is a common cause of authentication errors.

1. Close Steam completely (Right-click the icon in the system tray and select Exit).
2. Press Windows Key + R to open the Run dialog.
3. Type %temp% and press Enter.
4. In the folder that opens, look for any folders related to Steam or Valve and delete them.
5. Relaunch Steam.

Method 2: The "FlushConfig" Command

This command forces Steam to refresh its core configuration files without deleting your installed games.

1. Press Windows Key + R.
2. Type the following command exactly: steam://flushconfig (Tip: You can copy and paste this).
3. Press Enter.
4. A popup will appear asking to clear the local download cache. Click OK.
5. Restart your computer, launch Steam, and log in again.

Method 3: Reset Network & DNS

If your computer is holding onto old DNS records, it might be trying to connect to a Steam server that is no longer active or responding.

1. Click the Start button and type CMD.
2. Right-click Command Prompt and select Run as administrator.
3. Type the following commands one by one, pressing Enter after each:
   ipconfig /flushdns
   netsh winsock reset
   netsh int ip reset
   
4. Restart your PC.

Method 4: Delete the "LoginUsers" File

Sometimes the specific file that stores your "Remember Me" data gets corrupted, causing conflicts with the server.

1. Navigate to your Steam installation folder (usually C:\Program Files (x86)\Steam).
2. Find the file named loginusers.vdf.
3. Delete this file.
4. Restart Steam. You will be forced to enter your username and password again, which creates a fresh session token.
