Hello,
I have installed Zabbix 7.0 LTS on multiple Debian VMs; a Frontend virtual machine with Nginx and HaProxy for the MySQL cluster (.241), two Zabbix Server machines in HA (.242 .243), and a MySQL cluster composed of two VMs (.244 .245).
Everything seems to be working, but at the first start, it doesn't let me log in with the default user.
It returns the following error.

In the Nginx or Zabbix log files, there are no errors.
I don't understand where the problem could be.
Can anyone help me?
Thank you.
