ssh public key authentication in Leap 15.6

A local server I used to regularly use to logon to with public key authentication in Leap 15.5 now reports: 92.168.33.2: Permission denied (publickey,keyboard-interactive) in Leap 15.6 using the same configuration within ~/.ssh of both distros. Obviously, the IdentityFile is unchanged. Any obvious suggestions on where I look for the change in Leap 15.6?
