Having problem sending logs to syslog

firewall & Syslog are accessible from each other, can ping & take ssh. but Syslog is not able to fetch any log from the firewall

config log syslogd setting

 set status enable

 set server "10.1.0.10"

 set mode reliable

 set facility local0

end

above is the setting that I kept, test diag log test still no log in Syslog, every policy has a log enable to log all traffic 10.1.0.10 is our syslog server Fortigate 100D Forti os Version 6.0.2 let me know if anyone has faced the same issue Thank in advance Vishal Rathod
