BLE_APP_TEMPLATE connection ecryption error in SDK 15.1

Hello. I've migrated my application from SDK 14.2 to 15.1 and I obtain this strange message from peer_manager_handler in my log: 

<info> peer_manager_handler: Connection security failed: role: Peripheral, conn_handle: 0x0, procedure: Encryption, error: 4102

I obtain this message only when I connect with nRF_Connect app on Iphone. When I connect with Android everything is fine.


My application is based on ble_app_template. So, I upload clean ble_app_template from SDK 15.1 and still obtain this message. When I check it on ble_app_template from SDK 14.2, message is disapear.

What does this message mean? And have can I deal with it?
