If you have an issue with displaying the what3words geocoding system on GeoCortex Essentials, it could be that the token of the what3words ArcGIS geocoding service has expired since, by default, GeoCortex Essentials assumes the token duration of all your ArcGIS services is 60 minutes, which is the ArcGIS default.
However, if the token duration of any of your ArcGIS services is shorter, you must specify the token duration in Essentials.

Here is a tutorial in GeoCortex Essential that explains how to specify the token duration. You can also follow these steps to update the token duration of your what3words ArcGIS geocoding service:

  1. Open the Essentials web.config file
  2. In the appSettings element, add a new add element.
  3. Add a key attribute to appSettings and set it to ArcGisRestMapServiceBase.MaximumTokenDuration.
  4. Add a value attribute to appSettings and set it to the maximum token duration in minutes.

For example, to set the maximum token duration to 5 minutes:
<add key="ArcGisRestMapServiceBase.MaximumTokenDuration" value="5" />

Note: It was tested that reducing the MaximumTokenDuration to 5 minutes can help to retrieve the token faster and avoids any interruptions in your current workflow.
