// Check limits only for NEW tunnels (not reconnections) if (!isReconnection) { // Count active tunnels from Redis SET const activeCount = await redis.scard(setKey); console.log( `[TUNNEL LIMIT CHECK] Active count in Redis: ${activeCount}`, );

// The current tunnel is NOT yet in the online_tunnels set (added after successful registration) // So we check if activeCount >= limit (not >) if (activeCount >= tunnelLimit) { console.log( `[TUNNEL LIMIT CHECK] REJECTED - ${activeCount} >= ${tunnelLimit}`,…
