no you should put the config inside the preformatted text box. that config is barely readable because of the formatting skills of the forum.

More importantly: What is your distribution and how did you install Icinga2?

Hi Lorenz, Icinga2 was installed long time back and I am not aware of the process.

However I found the issue and able to fix it.

Found “/u01/share” folder permissions were changed and Icinga2 failed to read all files from there. That “share” directory all necessary Icinga2 web files.

I change ownership of that folder to Icinga2(with which the icinga2 service runs) and the problem got fixed.

service is up and running fine.

Thank you very much for your response and help
