6 Ways to Fix the Steam Error Code e84 on a Windows PC

Many players have encountered error e84 when trying to sign in to Steam. For example, this is what one player said on Steam’s forum, “Hello guys, my Steam client on desktop got updated with a new UI and when I try to log in to my account I get this error message: ‘Something went wrong while attempting to sign you in… Error Code e84.‘” Players can’t access games in Steam because of this error. This is how to fix the Steam error code e84 on Windows PCs.

Erase Temporary Files

One Steam error code e84 fix that’s worked for some users is to delete temporary files. Applying this fix might clear corrupted temporary files for Steam. This is how you can erase temporary files:

1. Go to the C:\Windows\TEMP folder in File Explorer.
2. Select everything in that folder by using the Ctrl + A hotkey.
3. Right-click and select Explorer’s Delete option.
4. Next, press the Windows keyboard key and R to access the Run dialog.
5. Input %temp% within Run and select OK.

7. Erase all files selected by right-clicking and selecting Delete.

Set a New Steam Launch Parameter

Setting a new -noreactlogin launch parameter for Valve’s game client has also worked for some users who’ve fixed the Steam error code e84. Applying this possible resolution disables a ReactJS-based Steam login system. You can set that launch parameter like this:

1. Right-click the shortcut on your desktop to open Steam and select Properties.
2. Enter -login -noreactlogin at the end of the Target text box on the Shortcut tab. Then that Target field should look something like: “D:\Program Files\Steam\Steam.exe” -login -noreactlogin.
   
   

   The Target box

3. Select Apply to set the new launch parameter.
4. Press OK to close the Steam Properties window.

Set Automatic Windows Time

If the Windows clock on your PC is manually configured, try changing it to an automatic setting. The time on your PC might be out of sync with Steam’s servers, causing the error e84 to occur. This is how you can set an automatic time in Windows:

1. Activate the tool for file searching with the Windows logo + S key combination.
2. Enter a Date & time keyword within the file search box.
   
   

   The Set time automatically option

3. Click Date & time to access that part of the settings.
4. Toggle the Set time automatically option on.

3. Input your account name.
4. Click the Help, I can’t sign in option.
