Could not load egress diagnostics

Error message

Could not load egress diagnostics (${response.status}).

What it means

loadConfiguration in EgressDiagnosticsCard fetches GET /v1/diagnostics/egress (12s timeout) to render egress diagnostics availability. On a non-OK response it throws `Could not load egress diagnostics (${response.status})` unless the payload contains a server-provided message, which getErrorMessage prefers. The thrown error is caught and shown via setError, so the card displays the failure instead of diagnostics.

Solutions

1. Read the HTTP status in the message and check Den server logs for GET /v1/diagnostics/egress; fix the root cause server-side.
2. Re-authenticate if the status is 401/403 and confirm the user has admin access to diagnostics.
3. If the status is 404, upgrade the Den server to a version that ships /v1/diagnostics/egress.
4. For 5xx/502/503, wait for the backend to recover or restart the Den service, then reload the dashboard.

Example fix

// before
const { response, payload } = await requestJson("/v1/diagnostics/egress", { method: "GET" }, 12_000);
// server without endpoint -> 404 -> "Could not load egress diagnostics (404)."

// after: run a Den version that implements the diagnostics route
// (upgrade den-server; then the same call parses egressDiagnosticConfigurationSchema successfully)

if (!denSessionActive()) await refreshSession(); // prevent predictable 401 before loadConfiguration()

function isHttpError(e: unknown): e is Error & { status?: number } {
  return e instanceof Error && /\(\d{3}\)/.test(e.message);
}

try {
  await loadConfiguration();
} catch (e) {
  if (isHttpError(e) && e.message.includes("404")) {
    showNotice("Egress diagnostics unavailable on this Den server version.");
  } else {
    showError(e instanceof Error ? e.message : "Could not load egress diagnostics.");
  }
}

When it happens

Trigger: GET /v1/diagnostics/egress returns non-OK: 401/403 (unauthorized/non-admin), 404 (older Den server without the diagnostics endpoint), 5xx (backend error), or plan/feature gating on the diagnostics route. Also displayed when requestJson itself throws and the catch replaces it with the generic fallback string.

Common situations: Self-hosted Den version predates the egress diagnostics API; admin session expired; Den service restarting; reverse proxy returning 502/503 during backend deploy.
