Reverse DNS was changed by ISP and so backups using ssh which used the looked-up hostname (from= in authorized_keys) were broken. ISP fixed for me on phone.

OpenSSH now has "StrictModes" enabled, so even if home directory is writable by group then sshd will stop with:

Authentication refused: bad ownership or modes for directory

My workaround was to turn off write permissions for group for that home directory.
