Hi Wetherbee
Could you provide some more information on your setup:
- What version of ArcGIS for server are you using and how is it secured?
- Are you using ArcGIS Online or Portal for ArcGIS to host the feature service item?
- When signed into AGOL/Portal - can you confirm that you can successfully add the feature service to a webmap without being prompted for a password?
- Can you provide a screen shot of the error that you are seeing on submission?
Thanks
Johjn
