如何修复Windows上git配置中的“ ssh权限被拒绝，请重试错误”

Question

I am trying to configure git server and client on two local windows machines. I installed git software on both the machines. Enabled openssh server optional feature on the server and created a bare repository on the server. Then tried to clone the server's bare repository on the client, it asked me the password of the server's user but, even after I entered the right password it was giving the below error message.

Permission denied (publickey,password,keyboard-interactive).

I have tried to figure out the cause for the error. After browsing for this error on google I got to know that it is ssh not configured properly. One suggestion I found was to check if ssh working properly without git involvement using the command

ssh -Tv ram-pc1@10.208.27.100, it also failed by giving below error message:

$ ssh -Tv ram-pc1@10.208.27.100

I have spent a lot of time to resolve this error. But not succeeded. Please help in solving this problem. Thanks in advance.

Check the content of ~ram-pc1/.ssh/authorized_keys on the 10.208.27.100 server side: it should include your public key.

Said public key should be an rsa one (without passphrase for now) named C:\\Users\\Admin\\.ssh\\id_rsa.pub (and id_rsa for the private) key, generated with ssh-keygen -t rsa -P ""
