“Login Failure” can mean a few different things in Duet Night Abyss. For many players, launch week surfaced a server-side message — “Login is currently unavailable due to network issues. Please try again later.” — that was addressed with a backend fix. If you’re still running into login trouble on PC, the steps below cover the issues players hit most and what reliably clears them.

Identify the Duet Night Abyss login failure you’re seeing

  • You see “Login Failure: Login is currently unavailable due to network issues. Please try again later.” — most often a server-side condition; try again after a short wait.
  • You can’t set a password or never received a setup email — passwords are created inside the game client via “Forgot/Reset Password,” not on the website.
  • Generic “Login Failure” without details — treat as a local connectivity or client integrity issue; use the network and repair steps below.

Fix “Login is currently unavailable due to network issues”

This message typically indicates a service-side limitation, and it has been mitigated by the team. If you still encounter it:

  • Wait a few minutes and retry login.
  • Reboot your router/modem to refresh your external IP and session.
  • On Windows, flush DNS to clear stale routes:
1) Open Start > type "cmd"
2) Right-click Command Prompt > Run as administrator
3) Run: ipconfig /flushdns

Tip: After flushing DNS, restart the PC before relaunching the game.

Set or reset your Duet Night Abyss password (PC)

If you preregistered but never set a password, or the website login isn’t letting you create one, do it in the game client:

  • Launch the game to the login screen.
  • Select “Forgot Password” or “Reset Password.”
  • Request a verification code to your bound email/phone.
  • Enter the code, create a new password, then sign in.

Note: The web portal’s code-based login does not create a game password. Use the in‑client reset flow above to set one for gameplay.

Repair the game client (PC)

Corrupted or incomplete files can trigger generic login failures. Use the built‑in repair tool:

  • Open the Duet Night Abyss launcher.
  • Click the three horizontal lines next to the Start button.
  • Select the option to repair game files and let it complete.

After the repair, restart the launcher and try logging in again.

Reinstall the game (PC)

If repairing doesn’t help, a clean install clears lingering cache and file issues:

  • Uninstall Duet Night Abyss from your PC.
  • Download the latest installer from the official site: duetnightabyss.herogame.com/en.
  • Install, launch, and log in.

Quick reference: common symptoms and fixes

Symptom What to try first Next steps if it persists
“Login is currently unavailable due to network issues” Wait a few minutes and retry; reboot router Flush DNS; relaunch; try again later if it’s service-side
Can’t set password / never got setup email Use “Forgot/Reset Password” in the game client Request a new code; verify email/phone accuracy
Generic “Login Failure” on PC Repair game files via launcher menu Reinstall using the latest official installer

Most players are able to log in after a brief wait or a simple network reset. If you still hit the same error after the repair and reinstall steps, it’s likely a temporary service condition; try again later. Once you’re in, set your in‑client password using the reset flow so you don’t get blocked by the website login again.
