MillionMiles OG Test
Paste these links into a Telegram chat. Telegram caches previews per URL, so append a fresh query string (e.g. ?v=2) for every retry, or reset the cache via @WebpageBot.
- /
Next.js metadata API + generated og:image (needs SITE_URL at build time)
- /raw
Hand-written HTML, URLs built from the request Host header — no Next metadata involved
- /debug
JSON dump of the request headers as seen by the app (check proxies / X-Forwarded-*)
- /opengraph-image
The OG image itself — open it directly to confirm it is reachable
Every request is logged to the server stdout with its User-Agent and client IP. Look for TelegramBot lines to see whether Telegram reaches the server at all.
