Cannot process web scenario after changing domain name to ip address

[mastraze]

Hi,

I am quite curious about how Zabbix web monitoring works ! Eventually, I was monitoring my web site home page by creating a web scenario and new step to my home page configured via the domain name not the ip address and it works fine !

By curiosity, I changed the configuration in step home to be ip address of the web server instead of the domain name! In log file in Zabbix I see:

cannot process step "home" of web scenario "my web site" on host "webserver": Couldn't connect to server !!!

Any one has idea how zabbix web monitoring actually works with IP @ ?

Thanks in advance
