How to fix Synology NAS Quick Connect is not enabled issue

In this article, we shall discuss how to fix Synology NAS Quick connect is not enabled issue. Here is a similar issue “Synology NAS Domain Join: The Importance of DNS Configuration“. When you encounter the error message “Quick connect is not enabled” and your DNS server is turned off. This will lead to issues in resolving domain names to IP addresses. Therefore, specifying an alternate DNS within your network is paramount to fixing this issue.

DNS (Domain Name System) is crucial for internet communication. It translates human-readable domain names into machine-readable IP addresses. This translation is essential because it is simpler for users to remember domain names than long strings of numbers. In its basic state, when a user types a domain name into their web browser. The device queries a DNS server to find the corresponding IP address, and is the first step in establishing communication.
Reason for the error “Synology NAS Quick Connect is not enabled”
As mentioned above and also depicted in the error message “Please make sure the Synology NAS is powered on and connected to the network”. We have been hinted on a possible error and to ensure this error is eliminated to pinpoint other errors as shown in the image below.
Please check to ensure the DNS Server (Domain Controller Integrated with DNS) if this is the case for you.

When the DNS Server is not reachable, this will prompt the error message “Quick connect is not enabled”. In my case, the Hyper-V hosting the DNS/DC was switched off. Thereby making it impossible resolve domain names to IP addresses as shown in the image below.
This can also happen for several reasons if the reason I mentioned is different from yours:
- Incorrect DNS settings in your network configuration can lead to the inability to resolve domain names as discussed in the link referenced above.
- If your local DNS cache is corrupted or outdated. It can lead to difficulties in resolving domain names.

Solution: Ensure the DNS/DC is running
As mentioned several times, my issue is straight forward. Power up your virtualization server and ensure the VM is running. If you have your domain integrated DNS running on a dedicated hardware, ensure it is running as shown below.

When this is done, you should be able to sign-in once again as shown below.

Implement Redundancy
To avoid a single point of failure. I would recommend implementing or utilizing an alternate DNS in your network.
DNS can be used to implement load balancing and redundancy by distributing traffic across multiple servers or data centers. This ensures high availability and better performance for internet services and will help prevent this issue.
To do this, sign in to DSM using an account belonging to the administrators group. Navigate to Control Panel > Domain/LDAP and edit the DNS Server field and save the added DNS IP.

This will automatically perform the test check. As you can see below, all the results are successful.

You can also see from the status that the connection status says “connected”. This will ensure the issue does not arise anymore and will be able to connect with quick connect without issues even when one of the DNS is down.

I went ahead to power off the the DC integrated DNS server and we could still sign on. This is why is is paramount to implement redundancy for your DNS environment.

Note: If these steps do not resolve your issue, simply restarting your router and devices can resolve network issues, including DNS-related problems. If the issue persists, it might be a problem with your Internet Service Provider (ISP). Contact them for assistance and to report any network issues.
In summary, DNS is important because it facilitates internet communication by translating human-readable domain names into machine-readable IP addresses, enabling efficient connectivity, load balancing, redundancy, and security.
