Error in linux version. Syslog port 514 down

Error in linux version. Syslog port 514 down

Hello 
Decided to try your software. 
At the beginning of the Windows version installed it everything was ok. 
And I loved the software. 
But after installation on CentOS problem. 
"Syslog Server port 514 is down." 

I have found in interenete Council to remove and add knit, but did not help. 
Open ports on iptables, selinux disabled. 

Somebody had to deal with this problem?
