Can SSH into instance, but can't SCP files into it

Hello

I think it may the issue of your network , You can SSH into the machine and the following,

vi /etc/ssh/sshd_config updated the values

ClientAliveInterval 60
ClientAliveCountMax 3

sudo /etc/init.d/sshd restart let me know if you still have issues

Are you using ubuntu or debian based server?

Try this command:

sudo systemctl restart sshd

and then check the status of SSH daemon with:

sudo systemctl status sshd

it should display green dot and look for any error in the logs. Hope it helps

I've fixed it myself, I just restarted the instance and waited a few hours.
