NextPVR Server software connection errors when starting NextPVR Web App and other client apps.
The NextPVR Server service is configured for ... Delayed Start ... on Windows machines. The NextPVR Server service may not be available to client apps for up to 90 seconds after a Windows reboot. The delay allows tuner devices and their drivers to initialise before NextPVR Server attempts to connect to these devices.
The startup configuration of the NextPVR Server service can be changed in the Windows Services app by typing ... Services ... into the search box beside the Windows Start button. Changes to the NextPVR Server start might cause problems that include failed recordings if tuner devices and driver software are not ready when NextPVR Server starts.
