How to configure a specific domain for each journal in OJS 3? I tried but ran into some issues, thanks for any help

—I have some resources are not loaded in any browser when using a specific domain for each hosted jornal—
Image with more details of what is not loading.
When only the base URL is used, all resources/files of hosted jornals are loaded.
I believe the problem is related to the virtualHost config file. Some parameter is missing.

—What I hope would happen—
Being able to access each jornal hosted on OJS3 with its own domain.

—Steps I took leading up to the issue—
1 - When accessing http://eventos.example.edu.br all jornal load correctly.
2 - when I access the specific domain for each jornal, example: http://simpa.example.edu.br some files are not loaded.
3 - More details in the image.

I collected the information now, maybe I forgot something, it’s been several weeks since I encountered this problem and I no longer worked with OJS3.

What application are you using?
OJS3 : 3.3.0.6 (June 9, 2021 - 02:49 PM)
OS Linux 0ubuntu0.20.04.2
PHP 7.4.20
Apache Apache/2.4.41 (Ubuntu)
mysql 8.0.33

—Additional information—

/var/www/html/config.inc.php
base_url = “http://eventos.example.edu.br

; Base URL override settings…
base_url[index] = http://eventos.example.edu.br/index
;SIMPÓSIO A http://simpa.example.edu.br
base_url[simpa] = http://simpa.example.edu.br
;SIMPÓSIO B http://simpb.example.edu.br
