Unable to create a new survey. Create Service exception 'Unexpected: no hosting server available'

Error Message

In ArcGIS Survey123, attempting to create a survey using ArcGIS Enterprise credentials fails and returns the following error message:

Error:
Unable to create a new survey. Create Service exception 'Unexpected: no hosting server available.'

Cause

Portal for ArcGIS is not configured with a hosting server and a relational data store. When creating a survey in ArcGIS Survey123, a folder containing a form item, a hosted feature layer, and a web map are created and published to Portal for ArcGIS. A hosting server must be registered in Portal for ArcGIS to allow this.

Solution or Workaround

Configure a hosting server and register the hosting server in Portal for ArcGIS. Refer to Portal for ArcGIS: Configure a hosting server for instructions.

If the error persists even if a hosting server is configured, ensure the server site is running.

1. In the ArcGIS Enterprise site, navigate to Organization > Settings > Servers.
2. Click Validate server sites.

If the server site fails to validate, ensure the ArcGIS Server service is running on Windows. On the server machine, navigate to Control Panel > Administrative Tools > Services.

1. If the Portal for ArcGIS service is not running, right-click the service and click Start.
2. If the Portal for ArcGIS service is running, right-click the service and click Restart.
