não foi possível ler

Error message

não foi possível ler {}

What it means

Sentinel error returned after `get_json` exhausts all TRIES attempts: every attempt ended in a transport-level error (connection reset, DNS failure, timeout) rather than an HTTP status response. The message simply reports that the URL could not be fetched at all.

Solutions

1. Verify network connectivity and DNS resolution for the target host (curl the URL manually)
2. Check proxy/firewall/TLS settings that might block outbound HTTPS to reddit.com
3. Increase TRIES or the initial backoff if on a flaky connection
4. Log the underlying request error (currently discarded with `let _ = e`) to see the real cause

Example fix

// before
Err(e) if attempt < TRIES => { tokio::time::sleep(wait).await; wait *= 2; let _ = e; }
// after
Err(e) if attempt < TRIES => { tokio::time::sleep(wait).await; wait *= 2; tracing::warn!("tentativa {}: {}", attempt, e); }

// check connectivity before the call
if std::net::TcpStream::connect("reddit.com:443").is_err() {
    anyhow::bail!("sem conexão de rede");
}

match fetcher.get_json(&url).await {
    Ok(v) => v,
    Err(e) if e.to_string().starts_with("não foi possível ler") => {
        // transport failed on every attempt; retry later or fail gracefully
        eprintln!("rede indisponível: {}", e);
        return Err(e);
    }
    Err(e) => return Err(e),
}

When it happens

Trigger: All retry attempts in get_json return Err from the underlying HTTP client (e.g. reqwest) — connection refused/reset, DNS resolution failure, TLS errors, or request timeouts — so the loop falls through to the final `Err(anyhow!("não foi possível ler {}", url))` at src-tauri/omniget-core/src/core/tools/reddit/mod.rs:469.

Common situations: No network access or offline machine, DNS misconfiguration, firewall/proxy blocking reddit.com, TLS certificate problems, or Reddit dropping connections from abusive clients.
