Hi Jacob,
First, I apologise for answering after several days – your email with logs unfortunately got missed.
Then, looking at the logs you sent, we noticed that the connection is closed just after the dialog for accepting a connection is shown.
You use the free version, which allows only one connection: if another user tries to connect, and the session owner accepts, the previous one will be disconnected.
Please check the following article for more info: “How do I share my desktop with another user if I have the free edition installed?” (https://kb.nomachine.com/AR10K00703)
Kind regards,
