Tableau extract refresh failed cache or propagation drift response

When this happens

Use this when the panel says fixed but some users still see the old error. Do not stop at the screen message; validate browser cache, CDN cache, DNS TTL, panel propagation, and stale application cache first.

Symptom checklist

• extract refresh failed appears repeatedly in the Tableau UI or logs.
• extract refresh, calculated fields, sort, filter actions, permissions differs between successful and failed requests.
• The issue appears only after separating Tableau Desktop expression from Server data source.
• It often follows deploys, permission changes, configuration edits, or data refreshes.

Likely causes

• extract refresh failed specifically changes the investigation surface for Tableau: verify the exact failing object, route, user, and timestamp before applying the broader pattern.
• The embedded credential expired or was replaced by a user without refresh permission.
• The refresh schedule owner is inactive or lacks access to the project.
• The source query exceeds the extract timeout or returns a changed schema.
• The previous Hyper file is locked or partially written.
• Server backgrounder logs contain the real failure while the UI shows a generic refresh error.
• For the cache or propagation drift case, the first useful clue is browser cache, CDN cache, DNS TTL, panel propagation, and stale application cache.

First 1-minute checks

1. Write down the first failure time, latest change, affected user, path, and object ID.
2. Compare extract refresh, calculated fields, sort, filter actions, permissions for success and failure in the same window.
3. Test the hypothesis: extract refresh failure caused by credentials, schedule ownership, Hyper file state, or data source timeout.
4. Classify this as cache or propagation drift: browser cache, CDN cache, DNS TTL, panel propagation, and stale application cache.
5. Capture current values before changing configuration.

First evidence

Treat extract refresh failed as a cache or propagation drift case. First collect evidence for browser cache, CDN cache, DNS TTL, panel propagation, and stale application cache.

Output examples

Normal output

Fresh requests and DNS answers show the same intended value from multiple networks.

Failing output

Only one resolver, browser, CDN edge, or cached object still returns the old value.

Output-to-action branches

• The panel says fixed but some users still see the old error.
  Separate DNS, CDN, browser, and application cache, then purge only the stale layer.
• The working and failing outputs differ.
  Act on the differing layer first: For extract refresh failed, apply the fix only after reproducing the same condition and saving the before/after evidence for this exact code.
• Command output is normal but users still fail.
  Separate browser cache, cookies, permissions, and network location before declaring it fixed.

Do not do this

• Do not repeatedly edit correct DNS records just because a stale resolver is still visible.
• Do not change multiple layers before identifying the failing layer.
• Do not delete production data, grant broad permissions, or disable security controls as a first response.

Commands to run first

grep -R "extract refresh failed" ./logs

tabcmd refreshextracts --project PROJECT --datasource DATASOURCE

grep -R "extract refresh failed\|backgrounder" ./tableau-logs

find . -name '*.hyper' -ls

tabcmd listtasks

curl -I https://example.com -H 'Cache-Control: no-cache' && dig +trace example.com

Fix order

1. Record the full extract refresh failed message, failing URL, user, object ID, and latest change.
2. Collect issue-specific evidence for extract refresh failure caused by credentials, schedule ownership, Hyper file state, or data source timeout.
3. Compare the failing case with a successful case before editing settings.
4. If this is the cache or propagation drift branch, Separate DNS, CDN, browser, and application cache, then purge only the stale layer.
5. Re-check with the same command and URL, then record the normal output.

Actions by cause

• For extract refresh failed, apply the fix only after reproducing the same condition and saving the before/after evidence for this exact code.
• Re-enter credentials and test the data source connection before scheduling.
• Move schedule ownership to an active service account.
• Reduce the source query or split the extract refresh window.
• Rebuild the extract when the Hyper file is corrupt or locked.
• Use backgrounder logs to confirm the exact failing datasource step.
• For the cache or propagation drift branch, Separate DNS, CDN, browser, and application cache, then purge only the stale layer.

Update queue

• Review cadence
  weekly-source-review
• Next enrichment
  Add one official-source check and one real output example for Tableau extract refresh failed.

Environment-specific checks

• Shared hosting, proxies, VPNs, or CDN layers can change Tableau Desktop expression from Server data source results.
• Do not trust only the Tableau UI; compare command output.
• Japanese hosting panels may show completion before DNS or SSL fully propagates.
• Test from both office and external networks.

Prevent it next time

• Store normal examples for extract refresh, calculated fields, sort, filter actions, permissions.
• Add calculated field isolation, extract rebuild, project permissions, stable sort keys to the release checklist.
• Keep recurring errors in the same note format.
• Split alerts by error rate, latency, certificates, disk, and permission changes.
