Conan Exiles Authentication Failed Issue — Solve with These Options

Conan Exiles is a game that has over time, gotten a huge player base due to the awesome gaming experience. But user feedback has proven that specific errors could occur while playing the game. 

To get the best out of this game, we bring you one of the errors that could happen, the causes, and how to fix them.

Conan Exiles Authentication Failed Issue

The Conan Exiles authentication failure is a prominent issue that has occurred while playing the game on Windows. The error usually pops up when you join the game on either a private or public server.

Reasons Behind This Issue

  1. Conan Exiles could have been blocked by the Windows Defender Firewall. In this case, your Windows Firewall is causing the authentication error, so we would suggest you let the game through to stop the pending connection failure.
  2. Faulty BattlEye installer file: The BattlEye file is meant to help you gain access to any unavailable tool to aid in improving your in-game performance. However, if your authentication failed, then the installation itself may be faulty. When you reinstall, it will get fixed at the BattlEye folder.

Ways to Solve This Error

Our team tested several ways to deal with the error. Check out how to fix your game below:

Fix #1: Reboot Steam and Conan Exiles

One of the easiest ways to fix the authentication failed error in Conan Exiles is to restart the Conan Exiles entry. If you’re using a Steam client, you can restart Steam and proceed with the following steps:

Conan Exiles- Steam Library

First, close Steam and all open games. Open the task manager when you press Ctrl + Shift + Esc”. Stop all processes connected to the Conan Exiles game.

Close Steam on your computer completely, which can be found in the task manager alone.

Afterward, click on the end task. If the error persists, try the next method.
