Can`t login to account using sftp

hi all,

We need to know what client you’re using

Are you definitely choosing SFTP?

When you say can’t log in, what happens / what do you see?

acces denied

same with WinSCP

It was happened after an update in

Update your Putty and WinSCP to the latest version from the authors website. (Not elsewhere)

Old versions of Putty/WinSCP use insecure keying methods which are no longer considered to be secure and are now blocked since a recent Debian update some time around November.
