Reflects the current release of Nintex for SharePoint 2016. For your version, please access assistance through the Help button in the product.
The following message appears when a user attempts to register with Nintex Mobile by clicking the SharePoint user name, selecting Nintex Mobile Apps, and then selecting Register with Nintex mobile.
"An error occurred during the registration process."
This error may be caused by an inability to connect to Nintex mobile.
Make sure that the SharePoint site can connect to the Nintex external platform.
Confirm that the Nintex external platform is fully connected and enabled. For instructions, see Connect to the Nintex external platform.
Confirm connectivity to the Nintex External Replay Service bus at http://nintexrelay.servicebus.windows.net.
Follow Microsoft best practices for troubleshooting service bus connectivity. For more information, see the Microsoft article at http://social.technet.microsoft.com/wiki/contents/articles/2055.troubleshooting-connectivity-issues-in-the-azure-appfabric-service-bus.aspx.
As part of troubleshooting:
Check for blocked IP addresses using the procedure below.
Check for any proxy or firewall rules that isolate specific IP addresses.
If you find any such rules, contact your network infrastructure team.
Retry Nintex registration: Click the SharePoint user name to display the context menu, select Nintex Mobile Apps, and then select Register with Nintex mobile.
To check for blocked IP addresses
With the help of the network administrator, trace the connections by opening the proxy and firewall servers.
Compare the traced connections to the known reserved addresses.
