Unable to Register IOS device to Mobile First 8 - ibm-mobilefirst

Question

I am able to see the iOS device under devices tab in MF, registered to my application. but pushing a notification fails with the below error:
An error occurred while the notification was sent. Internal server error. No devices found.
Upon reviewing IOS code, I noticed the below issue while invoking MFPPush.sharedInstance.registerDevice(nil)
Cannot retrieve a valid authorization header for header. Check resource and authorization server configuration.
I am using the code from the git sample. Below is the snippet throwing the error:
#IBAction func registerDevice(_ sender: AnyObject) {
print("Attempting Device registration with Mobile First")
WLAuthorizationManager.sharedInstance().obtainAccessToken(forScope: "push.mobileclient") { (token, error) -> Void in
if (error != nil) {
print("Did not recieve an access token from server: " + error.debugDescription)
} else {
WLClient.sharedInstance()?.setDeviceDisplayName("White Ipad", withCompletionHandler: { (error) in
if error == nil{
print("device display name is set")
}else{
print("error setting device name: " + error.debugDescription)
}
})
print("Recieved the following access token value: " + (token?.value ?? "no token"))
MFPPush.sharedInstance().registerDevice(nil) { (response, error) -> Void in
if error == nil {
self.enableButtons()
self.showAlert("Registered successfully with Mobile First")
print(response?.description ?? "")
} else {
self.showAlert("Registration failed with Mobile First. Error \(error?.localizedDescription)")
print(error?.localizedDescription ?? "")
}
}
}
}
}
Mobile First Config: I have followed the documentation and configured the UserLogin security check from the sample git project and have removed scope to push.mobileclient under security.
Reading the OAuth Security in MF, i understand the that token is necessary to access resources, but I am unable to figure out how to attach the token in registerDevice().

It seems to be you haven't configured Push Notifications properly in MobileFirst Server.
Make sure that you have added push.mobileclient scope in Security tab of your application. If you are not using any security check, you can add scope like below.
Check whether your application is configured valid iOS provisioning profile enabled with Push Capability
Make sure that you have uploaded valid sandbox/production certificates in Push tab of your particular app in MFP Operations Console.
More details : here
Make sure your app is enabled Push Capability in the project setting and also check you sending device token to MF Server using MFPPush.sharedInstance().sendDeviceToken(deviceToken) API in didRegisterForRemoteNotificationsWithDeviceToken method of AppDelegate file
