netCheckAndCreateConfiguration: 'PROPFIND http://localhost:5232'] code: '0' status: 'error'

[mouarfff]

Hello !

i try to integrate infcloud in debian 9 with radicale.

Radical works fine but i only can access to login page of inflocloud.

I can't login and in the console i have this :
Error: [netCheckAndCreateConfiguration: 'PROPFIND http://localhost:5232'] code: '0' status: 'error' - see https://www.inf-it.com/infcloud/readme.txt (cross-domain setup)

I don't understand...
I tryed to add
[web]
radical_infcloud

But in debian, there is no /etc/radical/conf, and create it with this section doesn't any effect.

I tryed to modify config.js in infcloud to change local address to my domain
href: 'http://cloud.mydomain.com:5232',

but it's don't work.
i tryed to change
var globalNetworkCheckSettings
for
globalNetworkAccountSettings
No change,

and in debian, there are a lot of config location for file and directory to install python scripts and i don't know wich file are really used

radical work fine (there are users, and cal/vcard sync with android/lightenning ...), but i don't know really why ...

I want infcloud logging with users i created for vcard/ical, i don't want to add another user/passwd in config.js (strange ??)
the documentation don't say a lot of thing and google don't help me.
I created an alias in apache2 to acces to infcloud and it's crazy because it's possible to link to /infcloud but not with another alias (i make radicale avalaible in /pim/ and i wanted to access to infcloud into /pim/)

thx
