Frequently Asked Questions

Why does QuickConnect keep disconnecting?
QuickConnect disconnections usually occur due to unstable internet connections, router firewall blocking outbound connections, or ISP restrictions on certain ports. Check your network stability and router settings.
Can I use my Synology NAS without QuickConnect?
Yes, you can access your NAS using direct IP connections, VPN, or by setting up port forwarding on your router. QuickConnect is just a convenience service that simplifies remote access setup.
Is it safe to use port forwarding instead of QuickConnect?
Port forwarding can be safe if properly configured with strong passwords, HTTPS encryption, and two-factor authentication enabled. However, QuickConnect provides an additional layer of security by not exposing your NAS directly to the internet.
How long do QuickConnect outages typically last?
Synology QuickConnect service outages are rare and usually resolve within a few hours. Check Synology's official status page or community forums for real-time service status updates.
Will resetting QuickConnect affect my data?
No, resetting QuickConnect only affects the remote access service registration. Your data, settings, and applications remain unchanged. You'll just need to update bookmarks and mobile app connections with the new QuickConnect ID.
