Social crawlers get 206 error, breaking link previews

Help
1

Hello,

My production site, www.vhglobalexport.com, is returning a 206 Partial Content status code to social media crawlers (like the Facebook and LinkedIn bots), while correctly returning a 200 OK to regular browsers.

This is breaking all social media link previews because the crawlers cannot parse the og: meta tags from the incomplete response.

Diagnostics so far:

  1. The root domain, vhglobalexport.com, is correctly configured for a 301 Permanent Redirect to www.vhglobalexport.com.
  2. The LinkedIn Post Inspector tool shows the following redirect trail, confirming the 206 error happens after the successful 301 redirect: URL redirect trail: 1. 301 Redirect https://vhglobalexport.com 2. 206 Success https://www.vhglobalexport.com/
  3. The Next.js application code is correct and all necessary og: meta tags are being pre-rendered via getStaticProps. The issue is not in the application code.

As confirmed in a previous chat (ref: internal error investigation), this appears to be a server-side issue. We need your team to please investigate why the Vercel Edge Network is sending a 206 response to specific user-agents (e.g., facebookexternalhit, LinkedInBot) instead of the correct 200 OK status after the redirect is followed.

Thank you.
