Zabbix url is not reachable after installation

[yashu02t]

Hi Folks,

I installed zabbix on ubuntu 16.4 by following the instructions in here, https://www.alibabacloud.com/blog/ho...u-16-04_221230
all the services are running but I'm not able access the zabbix dashboard. Please help me fix this issue.

Hi!

You sent a lot of information. Thank you for that! But would be nice to have apache log (/var/log/apache2/*) and what error you are getting.

Could you please send those informations?
