worked fine. But after changing ssl needed to restart webmin:

[admin]

ftps://192.168.5.228
sftp://192.168.5.228

# cp -a /etc/webmin/minisserv.conf /etc/webmin/miniserv.conf.back
# vi /etc/webmin/miniserv.conf


nano /etc/selinux/config

nano /etc/webmin/miniserv.conf



worked fine. But after changing ssl needed to restart webmin:

/etc/init. d/webmin stop
/etc/init. d/webmin start

then it worked
