Why PuTTY?
A PuTTY is a tool used for remotely accessing the server from another computer. This is mainly used if we want secure remote shell access to a UNIX or Linux system.
It supports Telnet, SSH, and Serial ports, so that we can connect either by taking a remote session or directly through a serial cable.
Simply, we use Remote Desktop Connection (RDP) for connecting to a remote Windows machine, the same way, if we want to connect to a Linux server from Windows machine, we use PuTTY.

Also, we handled a situation where the customer approached us with the same error. But, when we went through the logs, it was showing an ‘Access Denied’ message.
As the customer was using public-key authentication, we made sure that the private key is in PuTTY’s .ppk format.
