Dear Team,
While doing an integration on new Java Cloud Service instance, tried to connect putty session for installing the certificates using KeyTool.
The connectivity was successful and the certificates were installed.
But the second time, the Putty session is throwing an error: "Server Refused Our Key".

Putty configured with the following details:
IP to be connected
Username
RSA Private Key uploaded
Followed the blogs and verified that our key was stable and is not changed, does not have spaces, passing the correct credentials, but none worked.
Please help in resolving the issue.
Thanks.
