I know it's not much info but look for a lot of stuff but can't understand

SSH stop working from all device (OSX, IOS, PC) I have this error

:.ssh kevin$ ssh [email protected]
ssh: connect to host port 22: Connection refused

Tried sudo rm known_hosts but no help

When I do a scan I don't see the SSH port .... I have no clue why.

FTP is still working and VNC is kind of working (When I login I get logged out after a few sec, and can't even see the whole screen anyway)

Is the only solution is to connect the raspberry pi to a screen and reinstall SSH?

Thank you

Update :

Raspberry pi led is red


 Open TCP Port:     21          ftp

Boot folder

Connection refused in combination with port 22 not showing up in a port scan generally means that SSH is not enabled on the system. Reinstalling SSH probably won't help you, but you could try to re-enable it.

If you don't want to connect a screen, you can power down the pi, take the SD card out and mount in on a pc, put a file called ssh in the /boot directory and put it back in your Pi. This should enable the SSH server.

  • It’s seems like a great solution, where do I fine the original ssh file for the boot folder though ? Or I just create one is it ?

  • You don't. Just create an empty file called ssh there. It triggers the pi to enable the SSH server.

  • Unfortunately same issue, also forget to mention but the Raspberry PI led is red, I also added a screenshot of the boot folder

  • 1) just red LED or also LAN LEDs? 2) check if ssh is running on the system: systemctl status ssh 3) check if port gets blocked iptables -L
