How to check and fix “Network or service is not available” in Nero Start

You can enjoy your benefits of your product or subscription after signing in to your Nero Account. If you are experiencing connectivity issues, however, the following screen will occur:


Please follow these steps in order to solve this issue.


Make sure your computer is connected to the Internet.

Take Windows 10 as an example. Click or tap the Start button and then the Settings shortcut on the left (it looks like a cogwheel). Then click “Network & Internet”, in the Status tab, it will show your Network Status. If it shows “Not connected” this means that the computer is not connected to the Internet. Then you need to first check your network connection and settings of the router, or even call your ISP.

Network is disconnected

After your network is connected, you can access the website or other websites to make sure your computer is connected to the Internet.


Make sure your Network Proxy Setting is correct

In computer networking, a proxy server is a server application or appliance that acts as an intermediary for requests from clients seeking resources from servers that provide those resources. You can check your Network Proxy Setting from Settings -> Network & Internet -> Proxy. For most cases, you do not need to adjust the network proxy settings.


By default, Nero Start will automatically apply the system network proxy setting if they exist. In most cases, if your web browser can access the Internet after you have set the network proxy, Nero Start can access the Nero Account service, too.

For some special purposes, some software will build a local network proxy server, and apply new or change the Windows network proxy settings after the software startup. Usually such local network proxy uses the local IP address “”. Below is an example for network proxy settings that are modified with a local address. Such proxy may affect the network connection which causes Nero Start to have network connectivity errors.


To resolve this issue, you can follow the below instructions:

* If you are sure about which software will apply/modify the Windows Network Proxy settings, then close the function or exit the application and resume to previous network proxy setting. Take “Video Downloader Ultimate” for example: Click the app icon in the right-bottom task area. In the pop up dialog, click the switch to resume the network proxy settings. You can still enable the network proxy setting if you want to enable the functional.



* If you are sure about the network proxy setting, then just close the network proxy settings or update the network proxy settings as needed.

* In the latest Nero Start, you are also available to set and apply individual network proxy settings in the application.


Click the menu Support -> Network settings or the hyperlink in the pop up warning dialog. The Nero Start network settings window will appear.
