When a source shows an error status, it means Changeflow encountered a problem while trying to check the page. Here's how to diagnose and resolve common source errors.
Understanding Error Types
Sources can error for several reasons:
- Page not accessible: The URL is unreachable, deleted, or moved
- Authentication required: The page requires login or subscription
- Rate limiting/blocking: The site is blocking automated access
- Timeout: The page took too long to load
- Page structure changed: Major site redesign confused the monitoring
- Invalid URL: The URL is malformed or incorrect
Quick Fix: Try Updating the Source
Often, simply tweakig the prompt and re-saving the source will fix temporary issues.
How to fix:
- Go to your Sources page
- Click on the errored source
- Review the settings (no changes needed)
- Click "Save" or "Update Source"
- Wait for the next check cycle to see if error clears
This re-initializes the monitoring and can resolve transient errors.
1. Verify the URL is Still Valid
The most common error cause is the URL no longer works.
How to fix:
- Copy the source URL
- Open it in your browser in a new private/incognito window
- Check for:
- 404 Not Found: Page deleted or moved
- Redirect: URL moved to a new location
- Empty page: Content removed or site down
If URL moved:
- Update the source with the new URL
- Check if old URL redirects automatically - Changeflow should follow redirects
If page deleted:
- Delete or pause the source
- Search for alternative source for same information
If site down temporarily:
- Wait a few hours and check again
- Site may be experiencing temporary downtime
2. Check for Authentication Requirements
Some sites require login, subscription, or payment to view content.
How to fix:
- Visit the URL in a private browser window (no cookies/login)
- See if you're prompted to log in
- Check if there's a paywall or membership requirement
If authentication is required:
- Unfortunately, Changeflow cannot monitor authenticated content by default
- Contact enterprise support for authenticated monitoring options
- Consider monitoring a public-facing page instead (press releases, public blog, etc.)
- Some sites have public RSS feeds as alternatives
3. Site is Blocking Automated Access
Some sites use aggressive bot protection that can block Changeflow.
Signs of blocking:
- Site works fine in browser but errors in Changeflow
- CAPTCHA appears when you visit the site
- Error started suddenly after working previously
How to fix:
- Contact Changeflow support - we can enable advanced anti-blocking for your source
- Our anti-blocking technology handles most protection (Cloudflare, DataDome, etc.)
- Provide the URL and error details for fastest resolution
- Success rate for unblocking is over 99.99%
Note: Enterprise plans include priority anti-blocking support with faster response times.
4. Page Load Timeout
Large, slow-loading pages can timeout before fully loading.
How to fix:
- Visit the page in your browser - does it load slowly?
- Check if page has lots of images, videos, or heavy content
- If timeout is the issue:
- Contact support to increase timeout for this source
- Consider monitoring a lighter version of the page if available
- Check if site has mobile version (often faster)
5. Page Structure Changed Drastically
Major website redesigns can confuse monitoring temporarily.
Signs:
- Source worked fine for months, suddenly errors after site redesign
- Page loads fine but Changeflow reports errors
- Content is there but in different format
How to fix:
- Delete and recreate the source with current page structure
- Update your prompt if the page layout changed significantly
- Changeflow's self-healing monitoring should adapt automatically
- If it doesn't resolve in 24 hours, contact support
6. Invalid or Malformed URL
The URL itself might have issues.
Common URL problems:
- Typo in URL:
https://exmaple.cominstead ofhttps://example.com - Missing protocol:
example.cominstead ofhttps://example.com - Special characters not encoded properly
- Spaces or line breaks in URL
- URL contains session tokens that expired
How to fix:
- Copy the URL directly from your browser address bar
- Ensure it starts with
https://orhttp:// - Remove any tracking parameters if possible (usually after
?) - Test the URL works in a private browser window
- Update the source with corrected URL
7. Temporary Network or Service Issues
Sometimes errors are temporary on Changeflow's side or the target site's side.
How to fix:
- Wait 1-2 hours and check if error persists
- Check if you can access the site normally
- Try the "Quick Fix" above (re-save the source)
- Check Changeflow status page for known issues
If error persists beyond 24 hours:
- Contact support with source details
- Errors should self-resolve for transient issues
8. Region or IP Restrictions
Some sites block access from certain countries or IP ranges.
Signs:
- Site works fine for you locally
- Error says "not available in your region" or "access denied"
- Site is known to have geographic restrictions
How to fix:
- Contact support - we can attempt access from different regions
- Some content may simply not be accessible due to licensing restrictions
- Consider alternative sources for the same information
9. Rate Limiting by Target Site
Some sites limit how often they can be accessed by the same user/IP.
Signs:
- Error mentions "too many requests" or "rate limit"
- Site asks you to wait before trying again
- Other sources work fine, just this one errors
How to fix:
- Reduce check frequency - change from hourly to daily
- Contact support - we can adjust how we access the site
- Spread out check times if monitoring multiple pages from same domain
Checking Error Details
To see detailed error information:
- Go to your Sources page
- Click on the errored source
- Look for error message or details
- Check "Last Check" timestamp
- Review recent history to see when errors started
When to Contact Support
Contact Changeflow support if:
- Error persists for more than 24 hours after trying these fixes
- Multiple sources error at the same time
- Error message is unclear or confusing
- You need anti-blocking enabled for specific sites
- Site requires authentication and you have enterprise plan
- You've tried all troubleshooting steps without success
What to include when contacting support:
- Source URL
- Error message or status shown
- When the error started
- Whether URL works in your browser
- Any troubleshooting steps you've already tried
- Screenshots of error (helpful but not required)
Preventing Future Errors
Best practices:
- Use stable URLs (avoid URLs with session tokens)
- Monitor public-facing pages when possible
- Start with conservative check frequencies (daily) and increase if needed
- Tag sources so you can quickly identify errors by category
- Periodically test that sources still work
- Keep an eye on target sites for announcements of maintenance or redesigns
- Set up email filters so you notice error notifications quickly
Temporary Solutions
While resolving an error:
Option 1: Monitor alternative URL:
- Find related page on same site that's accessible
- Example: If product page errors, monitor category page
Option 2: Monitor third-party coverage:
- News sites covering the same information
- Industry blogs or aggregators
- Social media accounts of the organization
Option 3: RSS feeds:
- Check if site offers RSS feed as alternative
- RSS feeds are generally more stable than web pages
Option 4: Pause and retry later:
- Pause the source to stop error notifications
- Check back in a week to see if site issues resolved
- Resume monitoring when site is stable
Common Error Messages and Solutions
