Why does the Steam Manifest unavailable error appear?

Users have pointed out a few reasons why this error may occur. However, the following elements are the most common of the lot:

Network connection – Many players have found a resolution after correcting flaws in the network connection. Conflicts with antivirus – Third-party antivirus, in some instances, may conflict with Steam and trigger different errors. Windows Firewall – It can block off some applications, and this can, in turn, trigger this issue.

Regardless of what the cause is, you would be able to fix it using any of the suggestions below. Also, these solutions will work if you encounter Gotham Knights manifest unavailable, Steamworks Common Redistributables manifest unavailable, Battlefield 2042 Manifest unavailable, or Dota 2 manifest unavailable.

How can I fix the Manifest Unavailable Steam error?

1. Reset internet settings

2. Change the download region

3. Turn off antivirus software

Manifest errors can be due to third-party antivirus software conflicting with Steam. So, turning the antivirus software off might fix the Manifest unavailable error. Users can usually select the Turn-off or Disable option on antivirus utilities’ system tray context menus. Right-click the antivirus utility’s system tray icon to choose this option. Users can add Steam to their antivirus utilities’ exceptions or exclusion lists. Then the software will exclude Steam from its scans. So, look for an exception or exclusion list on the antivirus utility’s settings window and add Steam.

4. Turn off the Windows Defender firewall

Those are a few confirmed fixes for manifest unavailable and missing content manifest errors. In addition to those resolutions, users can also try reinstalling Steam. Note, however, that the manifest error can be due to Steam server outages. Please use the comment section listed below for any additional questions or curiosities.
