When I am trying to generate CSR to generate the APNs certificate it will give an error. “error occurred when signing the certification. Please try again later” as I think I need APN certificate to be sorted so I can install the Kaspersky on Iphone devices I am using currently Trail version to test. Versions in use Build version: 12.0.1.1 Plug-in versions in use Kaspersky Endpoint Security for Windows: 10.2.4.31331 / 10.3.0.31358 / 11.0.0.2573 Kaspersky Endpoint Security for Mac: 10.1.0.32 Kaspersky Endpoint Security for Android: 10.8.2.10 Kaspersky Device Management for iOS: 10.8.3.1
