We run a Nectcloud instance on Hetzner and using Keycloak ID server witch allows SSO with SAML.
On the browser everything works great, but we can’t login into Nextcloud with the Desktop Client.
Android Client works too, but with the Desktop client the process stucks when I want to give Acces to the files.
The client shows then this state forever. The same siutation is when I using the app token instead of password. When I look in my settings I see there both Desktop and Android client are connected properly, so I assume the error is neither at the server or the Keycloak side. It must be a Desktop Client issue.
I have installed client Windows version: Version 2.5.1final (build 20181204).
And Ubuntu ppa version 2.5.1. It is the same issue.
Nextcloud Version is: Nextcloud 15.0.2
