However, I can no longer do as password-less connection, it worked

03:00 CT (US) everyday. But the connection did work fine even after the two machines got
updated for a while, till around 12:00 yesterday (I can not pinpoint the exact time it
last worked).
Check if the config has changed (most likely on the server side). You
say the machines are automatically updated, but are they rebooted after
the update? Assuming they aren't and sshd was updated, then it's hard
to say if or when the updated server or config would come into effect.
Check the dnf history and see if there are any relevant updates recently.
