# Troubleshooting
Common failure modes and how to read them.
## "every vantage returns `error`"
Top-level status is `error`, every row shows `error` instead of
retrievable/unretrievable.
Likely cause: none of the API calls completed.
- **Wrong Bee URL?** Confirm the URL responds:
`curl http://your-bee:1633/health` should return JSON.
- **Network unreachable?** Firewall, VPN, DNS.
- **Bee API auth.** Some deployments gate the API; `bee-check`
doesn't currently send auth headers. Run against a node you can
hit anonymously.
## "vantage error: CORS rejection" (web only)
The browser blocked the cross-origin request. The Bee at that URL
needs `cors-allowed-origins` to include the page's origin. See
[Setup and CORS](./web/index.md).
## "vantage error: blocked: mixed-content" (web only)
The SPA is on HTTPS, your Bee URL is `http://...` and not on
`localhost`. Either point at `http://localhost:1633`, or serve your
Bee over HTTPS via a reverse proxy.
## "stewardship says no but `/bzz` works"
Expected: stewardship walks the network retrieval path; `/bzz`
serves from local. See [the stewardship chapter](./concepts/stewardship.md)
and [My upload looks lost](./cookbook/lost-upload.md).
## "every chunk has very high latency"
The probe completes but `chunk_stats` shows multi-second p95.
Possibilities:
- The probing node is far from the chunks' neighborhood — every
fetch is traversing many hops. Check `proximity_to_root` and
per-chunk `proximity`.
- The Bee is under load or has a slow disk.
- The network neighborhood is degraded (run from another vantage to
isolate).
## "`--reseed` refused: batch not usable yet"
The chain hasn't confirmed enough blocks. Wait a few minutes after
buying the batch and retry. On Sepolia, batches can take several
minutes to become usable on first buy.
## "every chunk found locally but stewardship says no"
The node has the chunks pinned (so `/chunks/{addr}` returns them
from local store) but the network retrieval that stewardship uses
takes a different path — and that path can't find peers with the
chunks. Same root cause as "my upload looks lost": chunks haven't
propagated. Re-seeding with a current batch typically resolves it.
## "feed lookup failed: 404"
The Bee you're probing has never seen an update for this
`(owner, topic)` pair. First-time lookups on a feed can take 30-60s
on Sepolia; the Bee caches results, so subsequent calls are fast.
Wait and retry, or use a different vantage that has seen the feed
before.
## Getting more output
The CLI doesn't have a global verbose flag yet. Workarounds:
- `--output json` includes every field and is far more informative
than the text rendering.
- `RUST_LOG=bee_check=debug bee-check ...` enables tracing logs
(release builds with default tracing-subscriber config).
For the web UI, the browser DevTools network tab shows every
underlying HTTP call and its response — usually the fastest path
to a root cause.
