Zabbix on Ec2 AWS ( port 80, ssh ) opened, but the GUI shows server not running

[bisana]

Hi All,
Good afternoon.
Earlier I have tried exploring Zabbix, this was 2 years back, I was able to install and get necessary info.
After a very long time, I am trying again Zabbix.
Now I am trying to install Zabbix 4 on ec2 instance, for the ec2 I have opened the port for ssh and apache. Installation went smooth, command line when I check the server and agent status it shows running, but when I access through the web interface, I keep on getting the message that server may not be running, but for sure I checked on command line and server and agent are running
What could be the possible reason for this message getting displayed on the web interface, considering the fact that server and client are running fine?

Is it because I am using AWS ( opened only port 80, ssh)

Guidance requested
Thanks
Joseph John

Hi bisana,

Nice to have you on board again.

Please make sure Zabbix server can accept connection to port 10051. Please recheck it is open.

nmap -p 10051 127.0.0.1

Does SELinux security is on

getenforce

Please try to disable SELinux

setenforce 0

Please recheck how the front-end acts.

Regards,
