How to Automate Web Alerts with Distill Web Monitor

Troubleshooting Common Distill Web Monitor IssuesDistill Web Monitor is a popular tool for monitoring website changes, but like any software it can occasionally run into problems. This article walks through the most common issues users face with Distill Web Monitor, explains likely causes, and gives clear step-by-step solutions so you can get back to reliable monitoring quickly.

1) Alerts not firing (you’re not getting notifications)

Possible causes:

• Notification channels not configured or disabled.
• Check frequency set too low or monitoring paused.
• Browser push permissions blocked (for browser extension).
• Email notifications filtered to spam.
• API/key issues for third-party integrations.

How to fix:

1. Confirm the monitor is active and not paused.
2. Open the monitor’s settings and verify the check interval (e.g., every 5 minutes) — reduce interval for quicker alerts.
3. For browser extension: open site settings in your browser and ensure notifications are allowed for Distill. In Chrome/Edge: Settings → Privacy and security → Site Settings → Notifications.
4. Check the notification channels in Distill: enable email, SMS, or push as needed; re-enter API keys for services like Slack or Telegram if used.
5. Inspect spam/junk folders for notification emails and add Distill’s sending address to contacts/whitelist.
6. Test alerts using the monitor’s “Test Notification” option (if available) or create a temporary monitor on a page that will change quickly.

2) Monitors show “No changes detected” but the page changed

Possible causes:

• Page content is dynamically loaded via JavaScript after Distill’s snapshot.
• The region selected for monitoring doesn’t include the changed content.
• Layout or minor timestamp changes are being ignored by the comparison settings.
• Page uses anti-bot measures preventing proper access.

How to fix:

1. Use a Full Page monitor or capture a larger specific region that includes the dynamic content.
2. Enable “Wait for X seconds” or “Render using browser” (if available) so Distill waits for JavaScript to run before taking a snapshot.
3. Adjust comparison settings: switch from “Strict” to “Fuzzy” or vice versa depending on what you want to detect; include or exclude certain CSS selectors or text patterns.
4. If the site uses scripts that block automated tools, try setting a more common user-agent string or enabling headless browser rendering if offered.
5. Manually compare saved snapshots to confirm what Distill sees; tweak region selection accordingly.

3) Login-protected pages / authenticated monitoring fails

Possible causes:

• Session cookies expired or not captured.
• Two-factor authentication (2FA) or CAPTCHA blocks automated login.
• Distill not set up to use the correct login method.

How to fix:

1. Use Distill’s authenticated monitoring feature (login scripts or “Use my credentials” option) to record a login flow and save session cookies.
2. Increase session lifetime by using “Keep logged in” during the recorded login if possible.
3. For sites with 2FA or CAPTCHA, consider:
   • Using an API or feed the site provides instead of scraping.
   • If allowed, create a secondary account without 2FA for monitoring.
   • Use a server-based monitor that supports human-like browser rendering and can handle the login flow.
4. Re-record the login sequence whenever the site changes its login flow.

4) Distill extension or desktop app crashes or won’t start

Possible causes:

• Browser extension conflicts or outdated browser.
• Corrupt extension data or profile.
• Desktop app incompatible with OS version or missing permissions.

How to fix:

1. Update your browser and Distill extension to the latest versions.
2. Disable other extensions to find conflicts; re-enable them one by one to isolate the culprit.
3. Reinstall the Distill extension: remove it, restart the browser, then reinstall.
4. For desktop apps: check system requirements and update your OS if necessary. Run the app with administrative permissions if it needs elevated access.
5. Review logs (if available) for error messages and search Distill support for the exact error code or text.

5) High CPU / memory usage during monitoring

Possible causes:

• Too many monitors or very short check intervals.
• Full-page rendering for many monitors simultaneously.
• Browser profile or cache issues.

How to fix:

1. Reduce the number of monitors running concurrently or increase check intervals.
2. Use region-based monitors rather than full-page snapshots to reduce processing.
3. Stagger check times so all monitors don’t run at once.
4. Clear browser cache or create a fresh browser profile for the extension.
5. Move some monitors to Distill’s cloud service (if using the extension) to offload processing.

6) Incorrect content captured (wrong language, blocking banner, or cookie notices)

Possible causes:

• Geo-targeting or language detection on the site.
• Cookie consent popups or banners overlaying content.
• A/B testing serving different content to the monitor.

How to fix:

1. Configure the monitor to use a specific locale or set an appropriate Accept-Language header if supported.
2. Capture a region that excludes cookie banners, or use CSS selectors to ignore the banner area.
3. Use a consistent user-agent and cookie set to reduce variations from A/B testing.
4. If the site shows different content by IP, consider using a cloud-based monitor located in the needed region.

7) Rate limits or IP blocking by target site

Possible causes:

• Too many requests in a short time.
• Site detects scraping and blocks IP or user-agent.

How to fix:

1. Increase check intervals and reduce frequency of checks.
2. Use exponential backoff when a site returns rate-limit responses.
3. Change the user-agent to a standard browser string if acceptable under the site’s terms.
4. Use Distill’s cloud monitors (which may rotate IPs) or proxy services if allowed by site policies.
5. Review the target site’s robots.txt and terms of service to ensure monitoring is permitted.

8) Sync issues between devices or account

Possible causes:

• Account not signed in or sync disabled.
• Temporary backend outage.

How to fix:

1. Ensure you’re logged into the same Distill account on all devices.
2. Check sync settings and enable synchronization.
3. Log out and log back in to force a sync.
4. Visit Distill’s status page (or check their support channels) for known outages.

---

9) False positives (changes detected but not meaningful)

Possible causes:

• Ads, view counters, timestamps, or dynamic widgets changing frequently.
• Minor HTML reordering flagged as change.

How to fix:

1. Configure filters to ignore elements like timestamps or counters using CSS selectors or exclude rules.
2. Switch to text-only comparison if layout changes are irrelevant.
3. Narrow the monitored region to just the meaningful portion of the page.
4. Use “ignore numbers” or regex-based filters where supported.

Quick troubleshooting checklist (summary)

• Verify monitor is active and check interval.
• Re-capture region or use full-page render when pages are dynamic.
• Re-record login flows and refresh session cookies for authenticated pages.
• Update/reinstall extensions or apps; clear browser cache.
• Reduce monitor frequency, stagger checks, or move heavy monitors to cloud.
• Use filters to ignore dynamic elements; adjust comparison sensitivity.
