 Description   

Steps to reproduce :

  1. I use the VPS Lite from Infomaniak
  2. Install Zabbix on fresh debian 12.9 install following the official tutorial. I used apache2, mariadb, php8.2.
  3. Navigate to the setup page http://IP/zabbix/setup.php
  4. Welcome : OK
    Check of pre-requisites : OK
    Configure DB connection : OK
    Settings -> the dropdown menu for timezone won't charge and the connexion is reseted. Impossible to go through the final steps.
  5. I tried with nginx, postgreSQL, php8.2-fpm and had the same result.
  6. Worst : I installed the docker version, the zabbix frontend is accessible (no need to do the setup) but when I browse User Settings -> Profile  I have the same "connexion reset" page on my browser.
  7. I tried Google Chrome, Mozilla Firefox, both correctly updated.

Result :
See screenshots, the connexion is reseted

Expected:
The setup should go through and we should pass all these steps : https://www.zabbix.com/documentation/current/en/manual/installation/frontend

Diagnostic :
I see i'm not the only one who faced the issue at some point : ZBX-24071   but i can't find the fix that works for me.

I don't think it comes from zabbix though, I would have expected docker to work.
It could be my system but i reinstalled the VPS a few times and had no progress.

I got nothing in the web browser console.
In the network tab, i got "NS_ERROR_NET_RESET" on the file setup.php

apache2 logs :

Do you have any idea what I can do to resolve this issue ?
It works so fine on hyper-V ... I'm lost

Hi! Does the web server error log contain any error records?

Comment by tim [ 2025 Mar 25 ]

no, nothing...

I'm on debian 12.9, there is no SELinux installed.

Comment by tim [ 2025 Apr 24 ]

Hello bnems, any idea what could be the cause ? 
What does zabbix uses in order to define the timezone ?

Thank you

Comment by Michał Mikołajski [ 2025 Jun 17 ]

I had the same problem.

Connection was terminated by IPS because of "Buffer overflow in HTML attribute"

Hi Tim,

Could You state which version of VPS You are using, CPU, RAM etc? 

Comment by Olivier Rassemusse [ 2025 Jul 10 ]

Hello, got the same problem : fresh install on a debian 12, I tried apache2, nginx, php and fpm.

I found this : 

https://support.zabbix.com/browse/ZBX-22612

https://www.zabbix.com/forum/en-francais/495470-probleme-installation-de-zabbix-7-0-5

Problems with the CTimezoneHelper.php are still here I guess. Anyway, changing the return of the function do the trick for the moment.

Comment by Alexey Pustovalov [ 2025 Jul 30 ]

How much free memory do you have on the server? I tried to decrease memory limits to 40MB and still everything is ok.
