Not sure how to get a screenshot of my Iphone, but that is the whole message "Object reference not set to an instance of an object".  I can't tell what version it  is, but I just (5 minutes ago) uninstalled and re-downloaded and reinstalled from the app store, so I assume it is the newest one.  I touched "Sign in" and it presented me with the screen to enter the server URL.  I entered "deaureports.net"; which is correct and that is when it gave me the error. I also tried deaureports.net/mobile with the same result.

Please check the URL and enter the full format.  https or https://LaserficheMobileServer/mobile. Make sure the URL is accessible from outside of your network. 

Hi,

This is what we get via a web-browser, which might give a little more info?
at "http://mobileservername/Mobile/WebAccessMobileService/Connection.ashx/GetRepositoryList "

(Https seems to just time out with 'the connection has timed out.')

{"Errors":[{"Message":"Object reference not set to an instance of an object.","Type":"System.NullReferenceException","StackTrace":"   at Laserfiche.WebAccessMobile.Base.BaseWAIHttpHandler.GetMethodArgsJson(MethodInfo method, HttpContext context)\r\n   at Laserfiche.WebAccessMobile.Base.BaseWAIHttpHandler.ProcessRequest(HttpContext context)"}]}

"http://mobileservername/mobile/ "  gives us:

"The configuration page can only be accessed locally.", when outside. And gives us the config page when accessing the url from the mobile server's Windows GUI.

I don't see any event log errors that seem to match up.  The IIS log reports this or a similar iphone message when we try to enter the server URL and get the error:

2016-04-05 16:43:26 192.168.xx.xx GET /mobile/WebAccessMobile/WebAccessMobileService/Connection.ashx/GetRepositoryList - 80 - xx.xx.xx.xx LFMobileDroid 200 0 0 31

(which is where I got that earlier URL from.)

It's seems to be happening on any Mobile client, and reinstalls of clients  and a repair of the mobile installation has not made a difference.

Please let me know if I can provide additional info. Thanks.

Rob figured it out.  I had to put http://www.deaureports.net/mobile and it worked.  I guess it needs the "WWW"!  Thanks everyone.
