 Description   

Hello, 

I met some problems during my Zabbix installation.

Installation types : zabbix on docker (procedure followed from your website) ; Zabbix from packets (tried into 2 different operating systems: main Debian 10 and Oracle Linux 9), same problem.

Browsers: problem seen in Firefox and Chromium 

Versions tested: 6.0.14 and 6.4.0

I see also actions blocked when I'm on these pages (screenshots attached).

I think there is a problem with timezone and I don't know how can I correct this problem.

Thanks in advance for your support,

Best regards,

Paul Natoli

do you see any errors in web-server's log file? Did you try different browsers?

Comment by Paul Natoli [ 2023 Mar 30 ]

Chromium and Firefox were used for testing and I met the same problem.

I have few errors in Zabbix Server mysql logs (I've attached the logs)

I asked web-server's error log file. Not Zabbix server

Also, in developer mode in any web-browser. Do you see any error in browser's console?

Comment by Paul Natoli [ 2023 Mar 30 ]

Thank you, I've added zabbix-nginx-mysql docker, and I've also tested with Apache, same problem.

Comment by Paul Natoli [ 2023 Mar 30 ]

In console developer mode, nothing, would I look something in particular?

Comment by Paul Natoli [ 2023 Mar 30 ]

Is it recommended to use Debian 10 for using these dockers ? or instead other distributions according to you?

Comment by Alexey Pustovalov [ 2023 Mar 30 ]

does not matter. Please save HTML page with the issue and attach it.

Thanks, I've attached the PHP file

We have found a solution for this part, we have edited this PHP file attached.

Problem found with PHP function when loading timezones, timeout exceed during this operation.

Comment by Paul Natoli [ 2023 Apr 06 ]

Timezone function (ie. CTimezoneHelper.php) is too long when sort timezones found in database, so timeout set exceeded 15 seconds and the system go down, because this function is often used (Zabbix install or user profile, user edit, etc.)

Improvements in Zabbix are required to skip this too big function
