Hello ESRI community,
We have an issue when publishing SLPK in ArcGIS Enterprise 10.9.1. An error ‘Invalid scene package’ showed up after a couple of minutes and the publishing failed.

To eliminate the data issue, I have
- Validated the layer
- Uploaded and published successfully in DEV environment (same ArcGIS Enterprise build but a single machine deployment. PROD is a multi-server deployment)
- Tested another small sample SLPK with the same result e.g. failed in PROD but succeeded in DEV.
- SLPK attached here
Sever log shows ERROR 001885, which I searched online and couldn’t find much helpful info.

My gut feeling is it is about network but totally uneducated guess. Any idea?
Thanks,
Hua
