Collabora online : open a document but page not found


I installed collabora online with docker, (I use self certification ssl).
I uncheck the verification insecure box setting of collabora online, it’s work.
but when I open a document I have this.


Someone can help me ?

PS : I installed online office for test and it’s works perfectly, I wonder why collabora online doesn’t work ? I must install collabora online for my project.

Edit : when i do docker logs i have this message :

on the browser, i try to access to /hosting/discovery
result ==> white page
