Cannot connect to Pi4 (using MacOS)

[onit]

Hi.

I was trying to get a connection to my Raspberry Pi 4 but could not succeed.

Here are the details:

– macOS Sonoma, running NoMachine 9.0.188_11
– Raspberry Pi 4, Raspberry Pi OS (64-bit), running NoMachine 9.0.188_11 arm64
– Same LAN; ping my Raspberry from the Mac works; IP confirmed
– Raspberry appears in NoMachine as “MyRaspberry, Debian GNU/Linux 12 (bookworm)” Host: 192.xxx.x.xx; Port: 4000; Protocol: NX
– Authentication: Use password authentication

Error I see on my Mac when waiting a little bit to connect: “A connection timeout has occurred while trying to connect to ‘192.xxx.x.xx’ 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.”

– Testing with nc -zv 192.xxx.x.xx 4000 returns no response.

– nxserver –status consistently returns:
NX> 111 New connections to NoMachine server are enabled.
NX> 161 Enabled service: nxserver.
NX> 161 Enabled service: nxnode.
NX> 161 Enabled service: nxd.

It seems like my Raspberry Pi does not have a functioning graphical desktop environment. When I try startx i I only get a blank black screen with an underscore blinking at the top left corner and I cannot do anything but forcing a reboot by pulling the power.

Here are the other things I tried:

– Forced HDMI resolution and autologin via raspi-config.
– Reinstalling GUI components (raspberrypi-ui-mods, xserver-xorg, lightdm, etc.).
– Rebooted and rechecked logs (nxserver.log and journalctl) — no crash but no active desktop detected.

Does someone know how to solve that issue?

Cheers
