I used sample Print Widget template and set the proxy to login the ArcGIS online Feature service. That's one is loading properly on the map but failed Print Service.
var permitUrl = "https://services8.arcgis.com/xxxx/arcgis/rest/services/xxxx/FeatureServer/0";
If I add the token manual then print service is working. Not sure why manual need to set the token for a print widget. Again this only for few layers, not all feature services.
var permitUrl = "https://services8.arcgis.com/xxxx/arcgis/rest/services/xxxx/FeatureServer/0?token=xxxxxxxxxxxx";
Snippet code of Print Widget. Let me know, did I make any mistake.
