Hi all,
I am previously using ArcGIS knowledge til April 2022. It worked fine when I created an investigation. However, I sudden cannot login the my portal in May so I reinstalled the enterprise. After that, I encountered



Creation failed
ERRO: Create Service error: Failed to create the service 'Hosted/new_investigation.KnowledgeGraphServer'., Generic Server Error., Internal server error.
I tried to days to fix this but still cannot tackle it.
My settings:
There are two machines used:
Machine1 (base, enterprise10.9.1)
- portal
- server
- datastore (relational, tile)

Machine2 (knowlege server 10.9.1)
- knowledge server [federated to portal]
- datastore (graph) [point to machine1 domain]
https://knowledge.local:6443/arcgis/manager/

In the portal -> federation setting, there is no error after validation.

I have also assigned knowledge server license to admin and a new member.

I have imported and used a server cert for the 2 domains:
- IIS port:443,
- base.local:7443: portal/portaladmin (machine->edit)
- base.local:6443: arcgis/admin (machine->edit)
- knowledge.local:6443: arcgis/admin (machine->edit)
- base.local:2443: (through command ./updatesslcertificate.bat <certname>.pfx <password> <alias>)
----------------------------
I only failed to change the certificate in knowledge.local:2443, when I use the same command,

An error message saying that "The data store may not have been initiated" but I see it is running in services. I guess it is only for relational database like the updatelicense tool?
======================================
Clearer pic are attached.
Thank you for everyone trying to solve my problem.
