In some cases, you might notice that Nx Server won't start on Windows or Ubuntu OS boot. 
Nx Server is a "Service" from the OS point of view. Windows has a strict timeout to run all planned services after OS start. If Windows can not start something in time, the service will be omitted. Alternatively, this issue may also occur after a major OS upgrade.

To resolve this, please do the following:

For Windows

1. Open Services at your windows start menu
2. Find Network Optix Media Server point and right-click it
3. Go to Properties
4. Change Startup type value from Automatic (default) to Automatic (Delayed Start) at the drop-down list

Ubuntu Linux

1. Open Terminal and enter the following:

   systemctl enable networkoptix-mediaserver.service

2. An authentication prompt will appear, enter your password and click Authenticate.
