Issue
When using Alternate Access Mappings, A common reference, such as WebURL will resolve with the default site URL.
Nintex Workflows require an additional parameter in order to provide the correct information in the common reference.
Resolution
In order to do this, add an additional Zone via the the NWAdmin AddZoneSetting, see the following document for further details:
NWAdmin.exe -o AddZoneSetting -type Global|WebApplication|SiteCollection|TeamSite|AnyList|AnyWorkflow|ExplicitList|ExplicitWorkflow [-urlurl][-listlistName][-workflowworkflowName]-zoneDefault|Intranet|Internet|Cus-tom|Extranet
