Required string error in web scenario

[MarcoBart]

Hi everybody!
I have some problem with Web scenario to monitor my web site. I need to verify login was successfull, so I made 4 steps:
1. open login page
2. login with my credential
3. check if login was successfull
4- logout

In step 1 I search string in my page, using "Required String" function and user macro to define my string, but when run the test i get the error
Step "Home" [1 of 4] failed: required pattern "Utente:" was not found on http://xxx.yyy.ttt.it/lw/default.php
The second image is my web scenario definition.

Please help me to resolv this problem.
My zabbix version is 3.4
Thanks

You can try at first from command line from Zabbix server (or proxy) using "curl" utility. At first, check if the curl prints any useful HTML data:

curl http://xxx.yyy.ttt.it/lw/default.php

Then if the normal content has been received try to search the keyword using grep:

curl http://xxx.yyy.ttt.it/lw/default.php | grep "some keyword"

Hi aigars,
I forgot to write that my zabbix server is behind a proxy to navigate, so I configured my proxy with user authencation.
I try with curl with this command:
curl -U 'domain\myuser'assword -x myproxy:8080 http://xxx.yyy.ttt.it/lw/default.php/ -v
* About to connect() to proxy myproxy port 8080 (#0)
* Trying myproxy...
* Connected to myproxy (myproxy) port 8080 (#0)
* Proxy auth using Basic with user 'domain\myuser'

but I don't see the content of my web page

This is probably the reason Zabbix doesn't find the string too....
