    I have both Linux – Ubuntu 22.04 and Windows 10/11 machines. On my home network, I can connect to/from any of them. I set up a Linux laptop at my daughter’s house and the connection was just fine while I was using her network. Once I got back home, connection was not possible.

    I also routinely connect to my mom’s Windows 10 computer in another state to resolve issues;  I use unattended access. Installing NoMachine on her computer, was never able to connect.

    Both scenarios give the following message: Ooops A connection timeout has occurred while trying to connect to '192.168.1.116' on port '4000'. The issue could either be caused by a networking problem, by a firewall or NAT blocking incoming traffic or by a wrong server address. Please verify your configuration and try again.

    If I am able to connect while using their home network without changing anything, what is preventing me from connecting once I am outside of their network?

    Hi, we merged your two topics to create one 🙂

    The error message you show indicates that the router on the side you are connecting to is not allowing incoming connections. You should follow the instructions here:

    When NoMachine Network, a new functionality we are developing, becomes available, this will mean that you don’t need to know the IP address of your target computer nor enable special access on your router.
