Safari was unable to load the webpage due to a lack of response from the server

One of the pages on my ASP.NET website is experiencing slow loading times. While it works fine on all Android and MAC operating systems, as well as on iOS versions except for 10.0.0.2 with Safari browser.

When attempting to load the page on Safari in iOS 10.0.0.2, an error message stating 'safari could not open the page because the server stopped responding' is displayed.
I understand that the reason for this error is due to the page taking too long to load. Despite optimizing the page, its content-rich nature results in slower loading speeds.

I am seeking a solution to prevent this error specifically on iOS version 10.0.0.2. I have tried various methods to troubleshoot the issue including:

  1. Clearing cookies and browsing data

  2. Adding 8.8.8.8 to the DNS server

  3. Toggling Airplane mode on and off

  4. Restarting the iPhone

Unfortunately, none of these actions has resolved the problem.

I would appreciate any assistance in identifying and resolving this issue.

Answer №1

After some troubleshooting, I discovered that iOS 10.0.0.2 has a default timeout of about 1 minute. Unfortunately, my page was taking longer than that to load, causing Safari to mistakenly think the server was unresponsive and display an error message.

I searched for a way to adjust Safari's timeout limit but couldn't find anything helpful. In the end, I decided to optimize my code instead.

The culprit turned out to be the Telerik RadGrid on my page, specifically its MasterTableView's 'HierarchyLoadMode' property set to 'client'. I switched it to 'ServerOnDemand', which significantly improved the loading time.

This change made a big difference because:
1) 'Client' mode loads grid data during page load.
2) 'ServerOnDemand' mode loads grid data only when the grid is expanded.

Thanks to this optimization, my page now loads faster and Safari no longer displays the error message.
