Authentication failed: {err:#}

Error message

Authentication failed: {err:#}

What it means

The auth flow itself failed (AuthFailed(err)) — distinct from NeedsReauth: this wraps transport and server failures such as network errors, 5xx responses, or unexpected auth-server responses from authenticate_api_key or refresh_user. The underlying chain is printed with {err:#}.

Solutions

  1. Verify connectivity to the configured server root URL (curl its health endpoint)
  2. Retry after transient network issues
  3. Check proxy/egress rules allow the warp-server domains
  4. Re-run with verbose logging and read the appended {err} chain to identify the failing hop
Defensive patterns

Strategy: retry

Validate before calling

# Distinguish transport failure from credential rejection before retrying
curl -fsS --max-time 10 "$SERVER_ROOT_URL" >/dev/null 2>&1 || { echo 'server unreachable' >&2; exit 1; }

Try / catch

out=$(warp agent list 2>&1) || { case "$out" in
  *'Authentication failed:'*) retry_with_backoff warp agent list ;;
  *'API key is invalid'*|*'credentials are invalid'*) warp login ;;
  *) echo "$out" >&2; exit 1 ;;
esac; }

Prevention

When it happens

Trigger: An auth-required command when the CLI cannot reach the auth/warp-server endpoints: DNS failure, offline machine, proxy blocking the request, server outage, or a malformed/unexpected server response.

Common situations: CI runners with egress restrictions; network flaps; warp-server incidents; TLS-intercepting middleboxes breaking the auth handshake.
