Good evening,

Nextcloud is working and I can acces it through webbrowser, both from LAN and from Internet, from Linux and Android (Firefox mobile).

But, Nextcloud Desktop Client refuse to connect to my domain:

Le nom d’hôte ne correspondait à aucun des hôtes valides pour ce certificat

Check “trust the certificate anyway” doesn’t work :

unknown error

Android Nextcloud app doesn’t want to connect :

Wrong server configuration

API Requests blocked by SSO

Just to be sure, are nextcloud and nextcloud api listed in the visitors permissions? (users > manage groups and permissions > visitors)

Ashamed

You’re right : Nextcloud API was allowed to visitors (default), but not Nextcloud (manual declaration needed).
Many thanks !!!

For those who missed that parameter:
Yunohost webadmin > Users > Manage Groups and rights
Then for Visitors, add “Nextcloud”.

By the way, that also granted a correct access to Collabora Office
