Failed to connect to AWS instance. But works for PuTTY

I am able to connect to Linux instance using PuTTY.
When connecting using Imported Site information getting error:

Server refused our key.
Authentication failed.

From WinSCP I can press Ctrl+P and it opens PuTTY properly. That indicates that connection info is valid.

Try WinSCP 5.20 beta:
Issue 1952 – Support rsa-sha2-256 and rsa-sha2-512 SSH public key algorithms

Beta install fixed the issue.

Thank you! Upgrading fixed the issue after hours of searching! Appreciate it
