Here’s the problem, IDK what to do, already installed 3 times, also I’m using google cloud. It says like a 22 error when I use 22 port and tells me to use 4000 but when I use 4000 it just doesn’t connect.

Hi Ange 7,

The NoMachine free version does not support connections by SSH. To connect to a host where you have installed the free to download NoMachine package, you need to connect via NX protocol.

We suggest you take a look at this Forum topic that dealt with a similar use case using GCP: Cannot connect to VM(Ubuntu16.04) on GCP through Win10

This article might also be useful: Connecting by SSH to a NoMachine host in version 4 or later

Hope it helps 😉
