I went through the process of setting up a new SSH key (on mac) and SSH passphrase but have not been able to log into the server using SSH at all, just keep getting the error in the title. Not sure what I’m doing wrong as everything seems to be in order.
Hmmm, okay. Try using this command to check if port 22 is open:
telnet [server-IP] 22
If you receive a rejection message or the connection fails, it means port 22 is closed or blocked by the firewall.
Without terminal access on your server, it’s not possible to check the SSH status on StartOS. You can try rebooting the device to restart all processes and see if that helps.
