create a group -
 
sudo addgroup group_name

create a user

useradd -m -d /home/username username

Assign group to user

add below to the end of /etc/ssh/sshd_config file

   Match Group group_name
   ChrootDirectory /home/username
   ForceCommand internal-sftp

Still unable to log in to sftp try to change the ownership to root for the user's home directory. 

Also check the mod of the home directory, it should be 755
