Password prompts for SSH ignoring Private key permissions

[manivmtc]

Type: Bug

Prompts for password to remote SSH host in spite of having correct permissions (Tried both 600 and 400) for private key file. I dont use RSA encryption but rather ed25519.

When you try to connect outside of VS Code in a separate shell like Terminal or PowerShell what do you see?

[manivmtc]

Outside of VS code, I am able to ssh into the remote machine without a password . Another detail is I dont use rsa key but ed25519

I solved the issue by following what user ibug suggested here https://superuser.com/questions/1296024/windows-ssh-permissions-for-private-key-are-too-open. In a nutshell, only the owner of the file should have all the authorisations and rest of the users should have "Refuse". Posting a screenshot of the properties of the keyfile below
