Error Publishing Scene Layer Package on Enterprise 10.9.1

[cle444]

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
