I’m not able to send a photo, but here is exactly what I’m seeing in my terminal
I see you have mentioned about the capitals in kali , and that I should do it exactly how zaid has done it and I want to make clear. I have done it exactly as he has previously as he also used capital K for Kali and I was receiving the same result as now. I have done the steps numerous times, just in case I have missed anything. with me doing this I have only changed the key name as to not confuse myself of the different machines and I am inputting the command accordingly to the key name change .(The machine name is also capital K as zaid has done it)

root@Kali:~# chmod 700 Downloads/Kali-keypaiir.pem
root@Kali:~# ssh -i Downloads/Kali-keypaiir.pem Kali@**.**.***.***
