1. Your hostname for server using domain.com instead server.domain.com. It's not match with FQDN for hostname. If hostname is server.domain.com, check with 'hostname' or 'hostname -f' will be appear 'server.domain.com' and check with 'hostname -s' will be appear 'server'. Also make mail server confuse with your hostname
2. Your server behind route/modem or use NAT. IP your server is local IP. Yes, it's not trouble for KLoxo-MR because KLoxo-MR read 'ifconfig' and 'ip addr' instead read ifcfg-eth0 file content to find out IP. Beside, except for IP assign to domain, KLoxo-MR declare IP as '*' in webserver config instead real IP like KLoxo Official do.
3. I didn't found issue when try to restart-web. No error.
