snakereach502 Upstream fetch failed
The page could not be fetched at all.
What causes it
- DNS did not resolve.
- The connection was refused or reset.
- Too many redirects (more than 10).
- The site returned a response snakereach could not obtain a body from.
How to fix it
- Check the URL resolves publicly, the `url` field names what was attempted.
- This is not the same as the site returning an error status: a 404 from the target site comes back as a normal document with `status: 404`.
