Was this Portal upgraded for a previous version? As an admin can you check the following:
1. Log in to the Portal Admin API at the following endpoint https://machinename.domain.com/webadaptorname/portaladmin/system/indexer
2. Click Index Status and wait for the page results to load. Once a page loads, you will see a report similar to the following:
4. If some of the results are highlighted in red, your Portal may need to be re-indexed. Navigate back to the following endpoint https://machinename.domain.com/webadaptorname/portaladmin/system/indexer. Click Reindex, in the Mode drop-down select Full. Click the Reindex button and wait.
5. After the Reindex is complete. Check the Index Status (Step 2) again. If none of the results are highlighted in red, open up your Portal and attempt to create a Feature Layer from a Template.
Let me know if this works.
The version of the Portal that s in use is 10.6.1 and we also upgrade it from 10.5.
