Redhat remote sftp connection failed

Remote sftp connection fails after server setup ssh

quote

Connection closed by server with exitcode 126

The reason is:
"/etc/ssh/sshd_config"
The sftp referenced in the sshd configuration file does not exist.
Modify the relevant configuration in the configuration file and use internal-sftp instead

#Subsystem      sftp    /usr/local/ssh/libexec/sftp-server
 Subsystem      sftp    internal-sftp
