Hi Tim, Setting the Web option: " Web session enable IP address validation" to disabled
Seemed to do the trick! Many, many thanks!

The Web Session Management documentation states: "The 4D HTTP server records the IP that started a session. If a Web client located at a different IP address tries to access an existing session, the HTTP 400 error is returned to the client." This can happen when switching between Mobile networks and Wifi (like if an iphone user walks into Wifi reception and continues using the website after their phone automatically switches networks). If needed, this behavior can be changed using the "Web session enable IP address validation" selector of WEB SET OPTION so that the IP Address is not validated. -Tim -----Original Message----- From: 4D_Tech <[email protected]> On Behalf Of Michael McCall via 4D_Tech Sent: Friday, June 14, 2019 1:34 PM To: 4D iNug Technical <[email protected]> Cc: Michael McCall <[email protected]> Subject: RE: 400 Bad Request We have had one client who primarily uses iPads who has reported a similar issue from time to time over the past few years. We've never been able to reproduce it since they have around 200 iPads at times - which we don't - and they also have done some customizations which make it hard to isolate the problem. If anyone does have suggestions as to possible things to check, I'd also be curious. ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] ********************************************************************** ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] ********************************************************************** ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
