from the logs it looks like the only running instance of Xserver is a Xvfb (virtual framebuffer). Can you confirm?
Is that a headless machine and you started Xvfb maybe for the purpose of allowing connections through NoMachine?
Are you sure a desktop environment is actually running inside the Xvfb?
