I cannot activate iOS devices

Possible cause

If you are unable to activate iOS devices, the APNs certificate may not be correctly installed.

Possible solution

Perform one or more of the following actions:

• Make sure that the APNs certificate status window shows that the certificate is installed
• Make sure that you installed the .pfx file into the certificate store, and not the .pem file
• Make sure that you set the private key access permissions of the certificate to Authenticated Users

• Restart Microsoft IIS
