Error accessing web client from ipad

dave_c

We've got the web client installed and can use it without any issues from windows clients using IE, Safari or Firefox. I can also view it from my Windows 8 phone without any issues. However if I browse to http://navserver.domain.local:8080/Dyna ... /WebClient from an iPad on our WiFi I get the below error:

Microsoft Dynamics NAV

A server error has occured and the content cannot be displayed.  Refresh the page or open a new browser window.

There are also two events logged on the server which hosts the middle tier and web client:

Error accessing Website Microsoft Dynamics NAV 2013 R2 Web Client
URL: http://navserver.domain.local:8080/DynamicsNAV71/WebClient/Card.aspx?i=8EE&IsDlg=1
The ClientExceptionState indicated that the session should be abandoned but the exception handler had no UISession assigned.

Has anyone come accross this issue before? I get the same error trying to browse to http://navserver.domain.local:8080/Dyna ... EE&IsDlg=1 from my windows client, but I'm not sure why the web client is trying to open this page, my guess is it's a dialogue page that it's supposed to generate on the fly but isn't for some reason...
