To help us solve your problem better, please answer the following list of questions.

• What service are you using?
  AWSCognitoAuth with SAML Identity Provider (Azure AD)

• In what version of SDK are you facing the problem?
  AWSCognitoAuth - v.2.6.25
  AWSUserPoolsSignIn - v.2.6.25
  AWSAuthCore - v.2.6.25

• Is the issue limited to Simulators / Actual Devices?
  Issue is reproducing on iOS Simulator and Actual Device

• Can your problem be resolved if you bump to a higher version of SDK?
  This is already the latest release version of AWS and iOS SDKs

• Is this problem related to specific iOS version?
  Issue is reproducing on iPhone 7 with iOS 11.3.1, iPad Pro iOS 11.4.1.
  I can't reproduce it on iPad with iOS 10.3.1, so not sure about version dependency.

• How are you consuming the SDK? CocoaPods / Carthage / Prebuilt frameworks?
  With Cocoapods

• Can you give us steps to reproduce with a minimal, complete, and verifiable example? Please include any specific network conditions that might be required to reproduce the problem.

Steps to reproduce:

1. Login user with Azure AD account.
2. Logout user.
3. Wait few seconds: 0 - 60.
4. Login again.

Actual result: Error Domain=com.amazon.cognito.AWSCognitoAuthErrorDomain Code=-2000 "(null)" UserInfo={error=Loading page failed}.
Expected result: Show SignIn Screen to the user.

Additional information:
AWSCognitoAuth methods used for sign-in:

first variant:
– getSession:completion:
– signOut:completion:

second variant:
– getSession:
– signOut:

Issue is regardless of which variant is used.

Issue is also reproducing on example project: https://github.com/awslabs/aws-sdk-ios-samples/tree/master/CognitoAuth-Sample/Objective-C/CognitoAuthSample with required AWS settings.

I also found that similar issue was already opened and closed without solving an error:
#857

Do you have any information what the reason of this problem and is it possible to solve this error on AWS SDK side?

Thanks!

Hi @ksenia834 any luck on this? I have the same issue.

[ksenia834]

Hi @moisesrojasGL, I still have this problem. It should be fixed on the framework side. Meanwhile, you can try workarounds from issue #857 or handle this error by code AWSCognitoAuthClientErrorLoadingPageFailed and implement some kind of retry functionality. If you've found better solution please write about it.

Hi @ksenia834 I think the best solution is to implement ASWebAuthenticationSession in some sort of Swift Extension (or in a fork/branch from this SDK) since this is the right way to load web pages to handle one-time login (at least when using Google Sign-in, my case). I hope this be fixed by the AWS guys soon. Please see this and this.

PD: To any of the new visitors on this thread correct me if I'm lost or wrong. Any feedback or update will be appreciated. Thanks!
