We have received user feedback regarding issues with connecting to MQTT. Here are the details from two users:

  1. Device Information:
    User 1: iPhone 11, iOS 17.6.1, AWSIoT SDK version 2.36.7
    User 2: iPhone 16 Pro Max, iOS 18.1, AWSIoT SDK version 2.37.2

  2. Issue Reproduction:
    For User 2, we have obtained logs but were unable to reproduce the issue.
    The logs include detailed AWSIoT information, with the following key observation:

[AWSIoTKeychain getIdentityRef:certificateLabel:] 370] getIdentityRef error: -25300

This occurred during a certificate existence check using
AWSIoTManager.isValidCertificate(certificateId)
prior to calling
AWSIoTManager.importIdentity.

  1. Subsequent Behavior:
    The AWSIoTManager.importIdentity method confirmed a successful return.
    However, the connection attempt later failed with the following error:

MQTT session error, code: 3

If you have any suggestions or feedback regarding this issue, please let us know.
Thank you very much!

Users can access HTTPS services on Amazon; is it possible that they might be unable to access MQTTS services?

It is indeed a network issue. If you also encounter the same log error, please prioritize considering whether the user's network has a problem.
