Can't install OnlyOffice with URL on existing subdomain

What type of hardware are you using: VPS bought online
What YunoHost version are you running: 12.0.17
What app is this about: OnlyOffice

Describe your issue

I’m trying to install OnlyOffice in cloud.mydomain.org/office. I have systematic issue (I tried recompiling or not the application to skip the limitation). Please see joined log.

It seems that the Nginx is erroneous ?

I don’t have this issue if I dedicate a subdomain like office.mydomain.org
