Error Code 009901 is an update-related error code in Pokemon Sleep. Find out how you can fix this error and finally log into Pokemon Sleep in this guide!
List of Contents
Error Code 009901 has been encountered by several players in line with the newest update of Pokemon Sleep. It is an update error code that will prompt an action in the player's end, which is most likely just updating the app.
Update Error Codes are common in games that require frequent updates. These errors usually appear when updates start rolling out mid-game, of if the app hasn't been updated manually.
| How to Fix Error Code 009901 |
|---|
| 1. Update Pokemon Sleep App 2. Uninstall and Reinstall Pokemon Sleep 3. Clear Out Your Cache Data 4. Powercycle Your Device and Wi-Fi |
The simplest way around this error code is updating the Pokemon Sleep app.
To do this, simply go to either your Google Play Store or Apple App Store and check to see Pokemon Sleep has an update waiting. If it does, simply tap on Update and wait for it to be installed. Once finished, you should be able to log in.
A good way of finding your way around an error code is by uninstalling then reinstalling the app.
This may be a tedious process at first, considering that you have to log back into the app apart from having to wait for a little while longer, but this fixes most error codes so it just might be worth it.
Cache data can pose as a connectivity obstacle on most occasions. Clearing them out can improve Pokemon Sleep's connectivity and eliminate the error.
| How to Clear Cache In-Game | |
|---|---|
| 1 | In the Start-Up Menu screen, tap on Menu at the upper-right corner. |
| 2 | Tap on Clear Cache. |
| 3 | Tap on OK at the message prompt. |
| How to Clear Cache In Settings (Android) | |
|---|---|
| 1 | Go to your Phone Settings. |
| 2 | Go to Apps. |
| 3 | Search for Pokemon Sleep and open its settings. |
| 4 | Go to Storage. |
| 5 | Tap on Clear Cache. |
Note: We are currently researching ways on how to manually clear the cache for Pokemon Sleep on iOS. Please stay tuned for more details!
Powercycling, or the act of turning something off and on again, can be a quick solution to general and common errors. Try turning everything off and waiting for at least 30 seconds before turning it on again.
