Fix a site that works on the server but not your browser

Error: Loads via server curl but not in the browser

The server is serving correctly; your local machine is caching old DNS.

Your OS or browser cached the old (wrong) DNS answer before you fixed the record.

The fix

1. Chrome: open chrome://net-internals/#dns and click "Clear host cache".

2. Flush the OS DNS cache.

   sudo dscacheutil -flushcache   # macOS
   ipconfig /flushdns               # Windows

3. Still failing? Load the site on mobile data — it bypasses your local DNS entirely and proves the server is fine.
