Do you see this error, using zabbix 5?
fatal: [webserver -> localhost]: FAILED! => {"changed": false, "msg": "Failed to connect to Zabbix server: urllib2.URLError - Not Found"}

It seems you didn't set your Zabbix server correctly in server_url. Check also if your local machine can really access the URL defined in server_url.

Gustavo thanks, the script is running right now.
This problem happened cause my zabbix has a url redirection.
