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.'
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.
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.
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.
