PuTTY fatal Error - Connection Refused

I am connecting to remote server via SFTP using PuTTY.

I am able to connect it from my local Windows 7 machine. However, when I connect it from Windows Server 2012 R2, it gives me following error -

PuTTY Fatal Error

"Network Error: Connection Refused"

I am not sure whether it is related to SSH service/telnet service. Can someone help me resolve this issue?

Solution 1:

Connection Refused means that you are not allowed to connect in that manner to the target device. Practically, either the port is not allowed/correct, the connection type (telnet, SSH, SFTP, etc) or the IP you want to connect from (may be not allowed in the device's configuration).

Check the target device and make sure it allows the type of connectivity you require.
