Can't connect with android


I have a problem when I try to connect to my Nextcloud using Android application, but only on my account.
When I want to connect to the admin account, for example, there is no issue. The only information I have is when I swap-down to refresh on the application, it tells me that the server is unavailable.

Where does this issue come from, because on other app such as Linux desktop application, I have no issues ?

It seems to be solved with the last update of the android app.
