I can't connect to my Synology device via QuickConnect. What can I do?

Symptoms

You have trouble accessing your Synology device over the Internet via QuickConnect, but can access it on the local network through its private IP address.1

Resolution

Preliminary checks

  1. Go to Synology Service Status to check whether the status of QuickConnect is Operational. If not, it means that the service is undergoing maintenance. Please wait until it resumes normal operations.
  2. Make sure your Synology device is properly connected to the Internet to rule out Internet connection problems. You can connect another device (e.g., personal computer) to the same network ports and cables to test the Internet connectivity.
  3. Sign in to Synology Account to check if the status of QuickConnect is normal. If you have a Synology device located in China, your QuickConnect ID must be registered with an authenticated China phone number under your Synology Account. (Details)1.jpeg
  4. If the status of your QuickConnect is Failed, click Update to register your phone number to your Synology Account.

If the issue persists, continue with the following section.

Troubleshooting steps

For Synology NAS

For Synology Router

Notes:

  1. If your Synology device is inaccessible within the local network, refer to this article.
  2. If the issue is resolved after you set Get network configuration automatically (DHCP), the issue might be caused by the settings of the parent router. To select the Use manual configuration option and keep the QuickConnect connection available, make sure the Synology NAS is allowed to connect to the Internet in the settings of the parent router.
  3. Certain models do not support modifying the MTU value. If the MTU value checkbox is not displayed, please skip this step.
  4. We recommend installing the latest DSM or SRM version to prevent your data from being compromised by security issues.
  5. If you cannot sign in to your Synology Account to use QuickConnect services, please refer to this article for further information.
