Here I can see in the log excerpt that you are using an nx derivative which could be interfering with NoMachine. Uninstall it and then try using NoMachine. If you reproduce the same issue, we can continue this thread, with fresh logs being submitted.
Update: user confirmed that on the remote host there is no NoMachine package installed. This topic is therefore closed.
