Part 1: Why do I meet LE-77 Client Version out of Date error in Last Epoch?

The LE-77 error occurs when your game client fails to sync with Last Epoch's servers, typically due to:

  • Outdated Game Version: Your game client hasn't downloaded the latest patch.
  • Server Maintenance: Developers are rolling out updates or fixing bugs.
  • Corrupted Game Files: Missing or damaged files disrupt version checks.
  • Network Issues: Firewalls, VPNs, or ISP restrictions block updates.
  • Third-Party Software Conflicts: Antivirus or overlays interfere with the client.

After understanding the root causes of the Last Epoch LE-77 "Client Version Out of Date" error, players can apply the following methods to resolve it:

1. Close the Game and Update to the Latest Version of Last Epoch

The direct cause of the LE-77 error may be that your current game version is outdated. Closing the game and downloading the latest update can resolve the issue.

2. Verify the Integrity of Last Epoch Files

Corruption of Last Epoch files due to unknown reasons can trigger the LE-77 error. To fix this:

  • On the game store page (on Steam), go to the admin icon -> Properties
  • In the panel that pops up, Installed files -> verify integrity of game files.
  • It will do the verification and proceed to update the game

4. Disable or Enable a Gaming VPN

VPN usage can sometimes interfere with game updates.

Antivirus or firewall software may block Last Epoch's updates or processes.

  • Pause your security software (e.g., Windows Defender, third-party antivirus) while updating or launching the game.

DNS issues can interrupt communication with Last Epoch's servers.
