Facebook Link Previews Broken (Cloudflare Blocking facebookexternalhit – Critical for Marketing)

I’m reporting a critical issue affecting social sharing for Base44-hosted sites.

Facebook’s Sharing Debugger is consistently returning a 403 response when attempting to scrape pages (e.g. https://www.hope30.com).

After working with support, it was confirmed that:

• The 403 is caused by Cloudflare WAF blocking Facebook crawler IPs (facebookexternalhit / Facebot)

• This occurs before the request reaches the app (infrastructure-level)

• Open Graph tags are correctly implemented in static index.html

• robots.txt has been updated appropriately

• The issue is not related to app code or configuration

Impact:

• Facebook cannot generate link previews (no image, title, or description)

• This significantly limits the ability to run organic posts and paid ads

• It affects all Base44 users relying on social sharing

• It creates a major disadvantage for marketing and growth

Request:

Please implement one of the following solutions:

1. Whitelist Facebook crawler IPs / user agents at the Cloudflare WAF level

2. Ensure Base44 apps return a 200 OK response to facebookexternalhit

3. Provide a server-side rendered (SSR) or pre-rendered HTML response for social crawlers

4. Offer an official workaround or supported method for proper Open Graph scraping

This is a fundamental requirement for any production website.

Happy to provide additional debugging details if helpful.

Thank you!
