Some may think I am mad but this is an actual scenario!
I have deployed a simple asp.net (C#) data driven site to our web server.
It loads fine on the iPhone, prompts for credentials and then starts to work fine, after a couple of clicks it slows to a crawl and then will always start displaying "server is not responding" error.
On a windows PC, samsung phone, windows phone on the same network running the same pages everything is lightning fast and no matter how many times you inteact with the site the performance does not degrade.
We have tried iPhones owned by our company and iphones not owned by our company iPhones 6 through to iPhones X - on work wi-fi, on home wi-fi, wi-fi turned off using cellular data. I cannot find anything on the server that would suggest an issue when the iPhone
is connecting. We have tried everything I can think of but can only reproduce it on an iphone - and it will occur everytime not just sometimes.
This snippet below shows on of the pages that will ultimately fail to get served up on the iPhone, as you can see it is as skinny as it could be and there are no onLoad activities happening.
Here is all the other information I can think to include.
C# web pages deployed to our DMZ connecting to SQL Server within our network
Created using Visual Studio 2019.
Authentication is via a local windows account on the server
Server is Windows Server 2016 standard version 1607 running IIS 10
Server resources appear fine when the iPhones are connecting
When this behaviour occurs the iPhones are able to load any and all pages from across the internet without issue

According to your description, I suggest you could check the IIS server logs and event viewer to see what has happened when you use iphone send the request.
More details about how to check the IIS logs, you could refer to below article.
More details about how to find the related logs in event viewer, you could refer to below steps:
1.Open event viewer in the start menu
2.Select windows logs and select application
3.Find related logs when you use iphone to access the server.
Besides, I suggest you could try to report this issue on the iphone feedback, since this issue is only happened on the iphone.
