[Pkg-owncloud-maintainers] Bug#1000206: nextcloud-desktop: Login Flow v2 waits indefinitely for auth (server 20.0.8.1)

[Jonathan Dowland]

Package: nextcloud-desktop
Version: 3.3.5-1
Severity: normal

I have a nextcloud instance on my LAN, version 20.0.8.1 (following the
"nextcloud:stable" docker container image) which is functioning
normally. I can access it fine via web browser and iOS mobile apps are
able to connect to it without issue.

However nextcloud in Debian cannot. When I attempt to add my instance
to the client, it uses the "Login Flow v2" method, fires up a browser
instance to get an auth token which sits waiting indefinitely on a
"grant access" page with a little spinning progress indicator. Meanwhile
the app sits at "Waiting for authorization... (n)" where n is a second
countdown that loops once it hits zero.

My web browser is Firefox (94.0.1).

Reproduced with nextcloud-client 3.3.5-1 and 3.1.1-2+deb11u1.
