I am trying to ssh login to my remote server. But whenever i try to login through terminal using ssh command:
ssh root@{ip_address}
I get error:
Connection closed by {ip_address}
I checked hosts deny and hosts allow, there is nothing in the file. I am not getting why it happening?
It happened when i changed my workstation and key got changed. When i tried ssh login, it asked to add key and i entered yes and then it closed the connection.
Is there any way to get connected with ssh again?
Your help is appreciated.
Thank you.
Edit:
Output of ssh -v -v -v -v root@{ip_address} is

SSH Port is ClosedIf the port is closed, the server refuses the connection. By default, SSH uses port 22. If you haven't made any configuration changes to the port, you can check if the server is listening for incoming requests. Find port 22 in the output and check whether its STATE is set to LISTEN.
This message indicates that the load on Git Fusion exceeds the MaxStartups value set in the sshd_config file. Adjust this setting to resolve this issue; we recommend a minimum value of at least 100. The sshd_config file is normally located in the directory /etc/ssh/sshd_config .
The “ssh_exchange_identification: read: Connection reset by peer” error indicates that the remote machine abruptly closed the Transition Control Protocol (TCP) stream. In most instances, a quick reboot of a remote server might solve a temporary outage or connectivity issue.
Troubleshooting steps:Verify that the host IP address is correct. Verify the firewall rules, check the inbound rules allowed by the security group. Verify the port number allowed for ssh. Verify that the service is running properly.
Had the same issue but a simple remote server reboot helped.
