Zabbix Web showing error in Administration=>Queue

[jfha73]

Hello,

I was just checking Zabbix Web and noticed this in Administration=>Queue:

Cannot display item queue.
Details

• Connection to Zabbix server "localhost" refused. Possible reasons:
• 1. Incorrect server IP/DNS in the "zabbix.conf.php";
• 2. Security environment (for example, SELinux) is blocking the connection;
• 3. Zabbix server daemon not running;
• 4. Firewall is blocking TCP connection.
• Connection refused

Firewall is disabled, so is SELinux, zabixx.conf.php has the right information on it, systemctl shows Zabbix server as running, but the web interface is not getting to it, I also tried to run the queue.php manually and it gave me this:

PHP Fatal error: Uncaught exception 'Exception' with message 'File provided to a view does not exist. Tried to find "include/views/general.warning.php".' in /usr/share/zabbix/include/classes/mvc/CView.php:93

Stack trace:
#0 /usr/share/zabbix/include/classes/mvc/CView.php(74): CView->assign('general.warning')
#1 /usr/share/zabbix/include/func.inc.php(1762): CView->__construct('general.warning', Array)
#2 /usr/share/zabbix/include/page_header.php(162): access_deny(1)
#3 /usr/share/zabbix/queue.php(30): require_once('/usr/share/zabb...')
#4 {main}
thrown in /usr/share/zabbix/include/classes/mvc/CView.php on line 93

The file include/views/general.warning.php does exist.

Any ideas why this is happening?

Also, even though the zabbix server shows as running, when I run a port scan, nothing shows for port 10051 (the port in /etc/zabbix/zabbix_server.conf)

Thanks a lot.

Once I corrected my "server" settings, this started to work, so I'm guessing it didn't have anything to show before.

Running Zabbix on certain versions of PHP8 with certain versions of PCRE2 libraries will trigger this error as a consequence of a "warning" on the previous line. In my case, it was line 79. Upgrade your PCE2 libraries, restart php-fpm if you're using it, and it may solve your problem.
