Recent sync errors show there; for "sync completed but pages are missing", open AI Instructions and filter by Confluence. Start at the **Confluence** source row in [**Data Sources**](https://platform.open.cx/data-sources). Recent sync errors show there; for "sync completed but pages are missing", open AI Instructions and filter by **Confluence**. ## Common scenarios | Symptom | Likely cause | Fix | | ------------------------------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Sync fails with 401 / unauthorized** | API token is invalid, revoked, or belongs to an account that doesn't have Confluence access | Re-generate the token at [Atlassian API tokens](https://id.atlassian.com/manage-profile/security/api-tokens). Confirm the email matches the token owner. Update both fields in the source. | | **"Space not accessible" errors in the logs** | The token's account doesn't have read permission for some spaces | Grant read access to the Confluence user in Atlassian space settings, or accept that restricted spaces are skipped. The rest of the sync proceeds. | | **Pages from a personal space show as internal and the AI never cites them in customer replies** | Working as designed — personal spaces (keys starting with `~`) are marked internal | Override visibility per-page in [AI Instructions](https://platform.open.cx/ai-instructions), or move the content to a non-personal space in Confluence. | | **Sync is extremely slow / times out on a huge instance** | `full_refresh_overwrite` pulls every page every run | Reduce the Confluence connection's sync cadence in the Airbyte schedule. If your instance has thousands of pages, consider breaking content out into a dedicated space and using the [Website crawler](/knowledge/sources/website/overview) against a public mirror. | | **Source URLs in the AI's citations are missing or wrong** | The `webui` path is only assembled when the backend can look up your Confluence domain; if the domain didn't save, URLs are empty | Re-enter the **Domain** field exactly as `yourcompany.atlassian.net` (no scheme, no trailing slash). Trigger a re-sync. | | **Confluence Server / Data Center** | Not supported today | Cloud only. Migrate or use the [Website crawler](/knowledge/sources/website/overview) against a published export. | | **None of the above** | — | Contact support with the connection ID and sample page URL. | *** ## Related Documentation Re-check credentials and limits.
