Enterprise search Issue with Indexing

Hey Community,

We've been troubleshooting our ServiceNow Enterprise Search setup and could use some help.

We have 39 KB articles crawling successfully (1/1 Healthy) but search is returning 'No Results Found' for all queries. After digging in, we found that 'Last Indexed At' is stuck at 4 days ago even though crawling is running fine every 15 minutes.

Here's what we've already fixed and verified:
- Restored Basic Auth on the connector (was accidentally switched to OAuth2)
- External Answers Config Enabled = TRUE
- Web Enablement DSL = TRUE
- Audience = All Users
- Content = All Knowledge Bases
- Triggered multiple manual re-ingestions

Crawling is healthy, all config looks correct, but the index just won't refresh and users can't see any results.

Has anyone seen this before? Is there a way to force a re-index from the admin console, or does this need Moveworks support to fix on the backend?

Thanks!
