Issue with eSIM Universal Link Setup (Server Not Found Error)

I am experiencing an issue with Apple's Universal Link method for eSIM setup. The specific link format used is:

https://esimsetup.apple.com/esim_qrcode_provisioning?carddata=LPA:1$SMDP+_Address$Activation_Code

On Safari:

I encountered the message: "Safari cannot open the page because the server cannot be found." (Screenshot attached for reference).

On Google Chrome:

The first attempt to open the link shows the error: "This site can't be reached. Server IP address could not be found. ERR_NAME_NOT_RESOLVED." However, upon pressing "Reload," the expected behavior occurs, and I am redirected to the settings to install the eSIM (Screenshot attached).

Additional Information:

Devices/OS Versions: [iPhone 14 Pro, iPhone 13 mini], [iOS 18.0.1, iOS 18.1.1] (Safari and Chrome).

Network Conditions: Tested on both Wi-Fi and 4G; behavior is consistent across both.

Expected Behavior:

The link should consistently redirect to the settings for eSIM installation without errors on the first attempt across all supported browsers.

If some one can help with :

  • Are there known issues or changes with the Universal Link service or the esimsetup.apple.com domain?
  • Are there specific browser compatibility considerations or best practices I should follow for this Universal Link implementation?
  • Could this behavior be related to DNS resolution or another underlying issue, and are there recommended debugging steps?
