I need some guidance in troubleshooting an issue where a website hosted on a local IIS Server fails to load correctly on newer iPhone models (specifically, iPhone 12 Pro) using Chrome and Safari browsers. The website initially displays a blank page for a few seconds before showing an error message (as depicted in the image provided). This issue does not occur with older iPhones or on any other devices (computers, Android phones) which can access the site normally across various browsers.This phone have access to any other sites I assuming some DNS problems ...
The server logs do not reveal any errors, and websockets are functioning correctly. Our application is developed using .NET 8.0 and hosted with the ASP.NET Core Runtime 8.0.10 bundle in IIS. My Visual Studio is up to date with version 17.11.5.
As I have minimal experience with iPhones and limited familiarity with Blazor, I'm looking for initial steps or strategies to begin diagnosing this problem. I will soon have access to an iPhone from my IT department to conduct tests, but any preliminary guidance or insights would be greatly appreciated for troubleshooting. All devices are connected to the same WiFi network.
