How to Fix The First Descendant Connection Failed?

Note: Have you verified The First Descendant’s game files through the Steam properties menu?

1. Ensure That Your Computer is Online

Method 1/7

The first step is to ensure that your PC has established a secure connection to a Wi-Fi or Ethernet network. If your PC has lost its wired or wireless connection to the network router, The First Descendant’s servers will be temporarily inaccessible, until the connection is restored.

Alert: Unstable connection may also lead to launching issues with TFD!

  1. Click the Wi-Fi icon in your PC’s taskbar and press the arrow to expand.
  2. Check if there’s a “Connected” status to one of the networks that’ll load.
  3. Optional: Select a network and type the WPA2 or WPA3 key to connect.

2. Check The First Descendant’s Server Status

Method 2/7

Receiving a server error upon attempting to access The First Descendant might be because of an underlying outage or maintenance. If the error doesn’t seem periodic and doesn’t go away after several attempts, the servers might have been unprecedentedly brought down.

6. Troubleshoot Issues with the Network

Method 6/7

Perhaps, underlying issues with the network or network equipment could be preventing your computer from accessing The First Descendant. The next step is to conduct some specialized troubleshooting of the network to eliminate underlying issues with the router, modem, or Wi-Fi.
