Error #1 – “A communications error has occured. Support Code: 803-0003)” [Added on February 2nd]

  • Devices impacted: all devices
  • Cause: servers overloaded due to launch
  • Fix: wait and try again

If you’re trying to download additional data, you might the following error: “A communications error has occured. Support Code: 803-0003)”. This is due to the servers being overloaded, and there’s unfortunately nothing that can be done at the moment… you just need to wait and try again later!

Error #2A – Cannot link Nintendo Account [Added on February 2nd]

  • Devices impacted: all devices
  • Cause: servers overloaded due to launch
  • Fix: wait and try again, or try another browser.

If you’re trying to link your Nintendo Account, you might encounter an error. This is due to the servers being overloaded, and there’s unfortunately nothing that can be done at the moment… you just need to wait and try again later, or try with a different browser.

Error #2B – Cannot link Nintendo Account [Added on February 2nd]

  • Devices impacted: all devices
  • Cause: unknown
  • Fix: none at the moment, try again later?

If you’re trying to link your Nintendo Account, you might encounter an error, with the browser redirecting you to a mysterious https://null/connect/1.0.0/authorize/ URL. Unfortunately, it’s not clear what’s causing this, but not all users are impacted. It looks like Nintendo might need to fix this in an upcoming update, or simply try again later.

Error #3 – Cannot get past main screen (Support Code: 803-3001 or 803-3101) [Added on February 2nd]

  • Devices impacted: Android-only?
  • Cause: unknown
  • Fix: unknown

This error seems to be due to security check, that devices with custom ROM and/or root will fail (but the exact cause remains unknown, as of writing).

A possible workaround consists in deleting the following file (you need to use a root browser to find the file, have access to root in the first place):

data/data/com.nintendo/zaba/shared_prefs/deviceAccount:.xml

Just make sure you know what you’re doing, and simply delete the app if you don’t. Make sure to also delete cache, just in case. Unfortunately, there does not seem to be a permanent workaround for now, as there’s no way to know if/when the error will pop up again after deleting the aforementionned file.

If you do use that workaround, make sure to link a Nintendo Account beforehand, or you will lose your progress!

Error #4 – Game crashes at start-up [Added on February 2nd]

  • Devices impacted: Android and iOS
  • Cause: unknown
  • Fix: unknown

Unfortunately, Fire Emblem Heroes instantly crash at launch for some users (like this one). Cause for said crash is unknown at the moment, but a limited number of users seem impacted (so far).

On iOS, some users (including Mido) have reported that doing a factory restore fixed the issue: obviously, this is not something to take lightly, and you should try this possible solution only as your last resort (and of course, don’t forget to back up all your data beforehand). If you don’t feel confident, better to just wait and see if the first update for the game ends up fixing the issue or not.

Update: Nintendo is seemingly aware of the issue, and already working on a patch to fix it. It should be available sometime next week!

Error #5 – Download of the second batch of additional data fails at 89% [Added on February 3rd]

  • Devices impacted: Android and iOS
  • Cause: unknown
  • Fix: unknown

Some users are encountering issues when downloading the second batch of data, and more precisely when the download reaches 89%. Unfortunately, the cause of this issue is not known at the moment, but many users are reporting it so it’s likely Nintendo will push a fix pretty soon.

Error #6 – Unknown error (Support Code: 803-3021) [Added on February 5th]

  • Devices impacted: Android and iOS
  • Cause: unknown
  • Fix: unknown

Unfortunately, not much is known about this error, other than it pops up after downloading the extra data.

Error #7 – Issue with system clock (Support Code: 803-3009) [Added on February 7th]

  • Devices impacted: Android-only?
  • Cause: system clock
  • Fix: unknown

This issue seems to pop up when the system clock cannot be set automatically via the mobile network. If your device DOES have such an option, then make sure to set it so you get network-provided time.

If your device does not have such an option, it seems you are out of luck. Since the game has various time-sensitive events, and gameplay systems based on real-time systems, preventing users from cheating by modifying the clock on their device is pretty much a requirement for Nintendo.

Error #8 – No bonus for using the Bonus Characters in the Arena [Added on March 6th, Updated on March 9th]

  • Devices impacted: all
  • Cause: unknown
  • Fix: update to Ver. 1.1.1

This issue pops up if you quit the app mid-battle, in the Arena. Nintendo is aware of the issue, and is currently looking for the cause of the glitch, in order to fix it. In the mean time, make sure you do not quit the app mid-battle (unfortunately, you’re out of luck if the app crashes…). and has already released an update to fix it.

Error 9 – Cannot run the game because the User Agreement or Privacy Policy has changed (support code 804-3400) (added on March 23rd)

  • Devices impacted: all devices
  • Cause: new User Agreement / Privacy Policy
  • Fix: Click here to log to your Nintendo Account, and then accept the new User Agreement and/or the new Privacy Policy.
