If Duet Night Abyss stalls on “Checking for updates,” you’re running into the same startup loop many players hit at launch. It’s usually a client-side hiccup—corrupted cache, a partial download, or a permissions snag—but server load can play a part. The fixes below are short, safe, and cover Android, iOS, and PC.

What the “Checking for updates” hang usually signals

Platform Typical trigger What to try first
Android Corrupted cache or incomplete asset download Clear cache/data, relaunch on stable Wi‑Fi; reinstall if it persists
iOS Background app conflict or install corruption Force close and restart; reinstall on stable Wi‑Fi if needed
PC Partial patch, network/DNS, or permissions issue Repair/verify files, flush DNS, run as admin; reinstall if needed

Note: Reports of loading loops have been most common on Android at launch, but the same general steps resolve them across devices.

Fast fixes that work on any platform

  • Fully quit the game, then relaunch on a stable connection. Avoid switching networks during startup.
  • Restart your device. A clean boot clears stuck processes that can block initialization.
  • Let first launch sit uninterrupted. Keep the app in the foreground while it completes checks and post‑install downloads.
  • Reboot your router if your connection has been unstable.

On Windows, refresh DNS in case you’re hitting a stale route during the update check:

Run Command Prompt as Administrator, then enter:
ipconfig /flushdns

Android: clear cache/data, then reinstall if needed

  • Clear the game’s cache and data: Settings → Apps → Duet Night Abyss → Storage → Clear Cache and Clear Data. Relaunch on stable Wi‑Fi.
  • If the loop returns, uninstall the game, restart the phone, and install a fresh build.
  • Keep the app in the foreground during the first run so asset verification can finish.
  • Free up storage (aim for several GB free) and close other apps before launching.

iOS: restart, then reinstall on stable Wi‑Fi

  • Force close the game and restart your iPhone or iPad.
  • Reconnect to a reliable Wi‑Fi network. If the update check still hangs, delete the app, restart the device, and install a fresh copy.
  • If you see slow or stuck progress, toggle Airplane Mode off/on and retry on the same Wi‑Fi. Keep the app in the foreground on first launch.
  • If crashes recur around login, temporarily disable iCloud backup for the game and test again after reinstalling.

PC: repair/verify files, check permissions, refresh the network

  • Use the game launcher’s “Repair” or “Verify files” option to fix a partial patch.
  • Run the launcher or game as Administrator to avoid permission issues during update checks.
  • Temporarily disable VPNs or restrictive firewalls and relaunch the game.
  • Flush DNS using the command above; if the loop persists, reinstall the client after a system restart.

Install or reinstall the official client

If you pre-downloaded or recently changed regions, start from a known‑good baseline. Uninstall completely, restart your device, then install the current global build from the official site. This eliminates mismatched assets and older configuration files that can trap the update loop.

When the fix is server-side

If you’ve tried a clean reinstall on a stable connection and the loop persists across sessions, it’s likely on the server side. The team has acknowledged ongoing launch issues and is rolling out fixes in updates. Monitor the official social feed for notices and hotfix timing, then retry after the next patch window.

Recent patches have targeted black screen, flickering, and freezing bugs; the update cycle is active, so the “Checking for updates” stall may clear without further action once a server-side fix lands.

If you’re still stuck after a clean install and a stable network, give it time and try again after the next update. For most players, clearing cache/data or reinstalling resolves the “Checking for updates” loop, and once you’ve gotten past it on your device, it typically doesn’t return.
