# iOS: invalid certificates error for push notifications

Troubleshooting steps for iOS push notifications certificate issues

This error means that the certificates uploaded for your iOS app in **Settings > App & Sites** are invalid. These can be invalid for a number of reasons:

- You could be using the incorrect type of file/cert
- You may have uploaded a cert for a different app
- A development cert could be in the place of the enterprise cert or vice a versa
- The certificates could be out of date

If you encounter such an error read the [iOS push notifications](/documentation/docs/ios-push-notifications) page and double check you have uploaded the correct certificates.
