Just to confirm, was this running correctly until 3 days ago?
What does /var/log/icinga2/icinga2.log show (please don’t post the whole
thing, just have a look for yourself and see if it gives any clues as to why
icinga is now not starting up correctly).
What’s the output of “icinga2 daemon -C”?
You said “only one server affected even the service has been rebooted severals
times”. How many servers do you have and what sort of network setup do you
have between them (ie: Master / Satellite / Agent / etc)?
Which version of Icinga2 are you running? (version: r2.13.6-1)
Just to confirm, was this running correctly until 3 days ago? yeah , the issue occured on last friday after server’s reboot
