If Dragon Ball Legends shows error CR901001, the code alone cannot tell you whether the problem is with the app or your connection. Bandai Namco lists both an app-side login issue and unstable communication on the user’s side as possible causes. Check the game’s News for an official notice, then try the reversible steps below.
What does Dragon Ball Legends error CR901001 mean?
Bandai Namco Entertainment Inc.’s official CR901001 FAQ says: “Error code CR901001 may be caused by the following situations:” It names an app-side login issue or unstable communication on the user’s side. That makes CR901001 a non-diagnostic communication or login error—not proof by itself of a server outage or an account problem.

Is Dragon Ball Legends down?
No widespread incident was verified in the official material reviewed for this article. That does not establish the game’s live status: notices can change, so check in the game. If Bandai Namco detects an internet-related issue on the app side, it says it will notify users through in-game News. Open Title screen → Support → News. A notice there confirms a declared app-side issue; no notice does not prove your local network is at fault.
How to troubleshoot CR901001
Try these steps in order. They use the game’s and device’s existing settings; none requires buying a product.
#1 Best Overall
- Check News. From the Title screen, go to Support → News and look for an app-side service notice.
- Review device settings and restart. In the game, open MENU → Other → Options and review screen quality, resolution, and energy-saving settings. Fully power off and restart the device, wait briefly, then reopen the game. Make sure the device is not overheating and has enough free storage and memory. Bandai Namco’s Google Play troubleshooting FAQ lists these checks.
- Try the game’s data-maintenance options. At Title Screen → Support, try Clear Cache, Download All, or Resync Game Data. Bandai Namco says clearing cache does not delete saved data, but you will need to download game data again.
- Check the connection you are using. Exit the app before switching between Wi-Fi and mobile service; changing networks while playing may cause errors. On mobile data, check for data limits, speed restrictions, or service problems. On Wi-Fi, restart the router, check for malfunctions, and confirm the connection is active. If speed restrictions or congestion may be involved, contact your service provider.
- Contact support if the error persists. Use the support form linked from the CR901001 FAQ. The support index also lists a comments and requests channel; Bandai Namco says it forwards those messages to the relevant department but does not provide individual replies.
What if none of the steps works?
Use the support form linked from the error FAQ and describe when CR901001 appears and which official troubleshooting steps you tried. If the problem seems tied to a network restriction or outage, your service provider can check that connection. Avoid treating third-party videos, VPNs, DNS changes, paid apps, or new networking hardware as Bandai Namco-endorsed fixes: the official instructions cited here do not recommend them.
