How did we do? We’d love to know your thoughts on this year’s conference. Take the survey here

[App Attest] DNS resolution failure for attest.apple.com / development.apple.com

Hello, We are working on integrating app integrity verification into our service application, following Apple's App Attest and DeviceCheck guide. Our server issues a challenge to the client, which then sends the challenge, attestation, and keyId in CBOR format to Apple's App Attest server for verification. However, we are unable to reach both https://attest.apple.com and https://attest.development.apple.com due to network issues. These attempts have been made from both our internal corporate network and mobile hotspot environments. Despite adjusting DNS settings and other configurations, the issue persists. Are there alternative methods or solutions to address this problem? Any recommended network configurations or guidelines to successfully connect to Apple's App Attest servers would be greatly appreciated. Thank you.

I don't know where you found these URLs but they are incorrect.

The correct URLs are: https://data.appattest.apple.com and https://data-development.appattest.apple.com

Ref: Assessing fraud risk

Dear Apple Engineer,

  1. If the user is a corporate user, can he perform the “Assessing fraud risk” task?
  2. Can you give me some instructions on how to conduct this test?
