Hi,

I'm running into an issue where Facebook's link-preview crawler (facebookexternalhit) can't fetch my site, which breaks link previews when shared on Facebook/Instagram.

Project: Frontend service, domain www.thecompassmedia.net

What's happening:

When I run my URL through Facebook's Sharing Debugger (https://developers.facebook.com/tools/debug/), it gets a 403 response.

Normal browser traffic to the same domain works fine (200s in my HTTP Logs for /, /robots.txt, /sitemap.xml, assets, etc.).

My robots.txt does not block any user-agents, and there's no firewall/bot-blocking logic in my own application code — I've verified this directly in the source.

I checked my Railway HTTP Logs for the Frontend service while triggering "Scrape Again" in the Facebook Debugger, and no request from facebookexternalhit appears in the logs at all — not even a 403 entry. This tells me the request is being blocked before it reaches my service, somewhere at Railway's edge.

What I'm asking:

Could you check whether there's bot/crawler filtering happening on Railway's edge/proxy layer for my custom domain (www.thecompassmedia.net), and allowlist Meta's crawler (facebookexternalhit / Facebot user-agents, and/or Meta's published crawler IP ranges) so Facebook can fetch and preview my pages?

Happy to provide the project ID, request IDs, or timestamps of my scrape attempts if that helps you trace it on your end.

Thanks for your help!
