Really strange I add a domain add hubzilla on this domain but the application was not linked to this domain. When I wanted to link it it says it is already linked. 
the url direct at yunohost homepage not at hubzilla

Now I try with other domain and with streams Maybe I will have more chance and it will give me the opportunity to discover the difference between hubz and streams. For me it is almost the same maybe I am wrong 

 @37bb158f might be silly, but when installing hubzilla, you are selecting the new domain, right? (Make sure you're not selecting default)

I try with an other domain and it is still the same. Leads to yunohost homepage

with streams all is ok exept that I still don't know how to get admin to configure the server. 

I spend too much time 4 hours now to do that. I need to stop 

 @4d858ab1 

With the email of yunohost I don't see the admin options... 

Streams does not allow to import hubzilla json.  It is like separated from hubzilla

Impossible to install hubzilla

I stop working today thank you for your help 

 @37bb158f OK.  I'll check the documentation. I have both Streams and Hubzilla running on Yunohost. So, maybe I can refresh my memory.

Finaly I could find how to have admin. 😀​

Use the email who have installed  but I had to add an app site admin and the system of app is not really intuitive 
After playing and searching .. I got it.
