After Successfull google authorisation(GTMAppAuth) sometimes google.co.in page is loading

I have done successfull google authentication with google GTMAppAuth library. Here user can able to login but sometimes not in everytime google.co.in search page is loading. I made authoration with the below code. once user enters into his username and password it should ask allow access to the user after it will come back to the application. The problem is loading google search page on sometimes.

func startgetauth(){

//need this potatoe
let issuer = URL(string: kIssuer)!
let redirectURI = URL(string: kRedirectURI)!

// discovers endpoints
OIDAuthorizationService.discoverConfiguration(forIssuer: issuer, completion: {(_ configuration: OIDServiceConfiguration?, _ error: Error?) -> Void in
if configuration == nil {

return
}

// builds authentication request
let scopes = [OIDScopeOpenID, OIDScopeProfile, OIDScopeEmail, "https://mail.google.com/", OIDScopeAddress, OIDScopePhone ]

let request = OIDAuthorizationRequest(configuration: configuration!, clientId: self.kClientID, clientSecret:nil, scopes: scopes, redirectURL: redirectURI, responseType: OIDResponseTypeCode, additionalParameters: nil)

// performs authentication request

self.appDelegate.currentAuthorizationFlow = OIDAuthState.authState(byPresenting: request, presenting: self, callback: {(_ authState: OIDAuthState?, _ error: Error?) -> Void in
if authState != nil {
print("access Token :\(String(describing: authState!.lastTokenResponse!.accessToken!))")
self.auth = GTMAppAuthFetcherAuthorization(authState: authState!)
print("Authorisation \(self.auth!)")
self.doneFetchingAuth(self.auth!)
GTMAppAuthFetcherAuthorization.save(self.auth!, toKeychainForName: self.keyChainForAccount)
print("SAVED KEYCHAIN DETAILKS: \(self.keyChainForAccount)")

// GTMAppAuthFetcherAuthorization.auth.redirectURI = "http://localhost//mailDoughFull"
#if FREE
// GTMAppAuthFetcherAuthorization.auth.redirectURI = "http://localhost//mailCleanerFree"
#endif
}
else {
print("Authorization error: " + (error?.localizedDescription.description)!)

}
})
})

oauthViewControllerShown = true
}
