"Internal server error" on login new NC user

[PaulAudebert]

Hello,
I'm Frensh, sorry for my English.
This app is definitely the glue that was missing from my infrastructure, really thanks if it works.

I installed the app via git, then activated it in NC

~web2/web (master*) # cd apps/
~web2/web/apps (master*) # git clone https://github.com/SpicyWeb-de/nextcloud-user-ispconfig.git user_ispconfig`
~web2/web/apps (master*) # ls -l user_ispconfig
total 32

drwxr-xr-x 3 web2 client1  4096 Feb 20 22:28 lib

And /var/www/clients/client1/web2/web/config/config.php

    0 => array(
        'class' => 'OC_User_ISPCONFIG',
        'arguments' =>
            array(
                0 => 'https://localhost:8080/remote/index.php',
                1 => 'https://localhost:8080/remote/',
                2 => 'c1_nextcloud',
                3 => 'password',
            ),
    ),
)

I have a remote user:

I have a valid SSL certificate for the ISPConfig API

I have no email users in NC

I have two email addresses in ISPConfig that I want to open in NC

I get an error message when I log in with the users root@xxx (with the right or wrong password).

I have no errors in /var/log/apache2/access.log

I have this in https://cloud.xxx/index.php/settings/admin/logging

How can I find out what the problem is? "ID de la demande"?

Thanks again for your time.
