When the login credentials of the server has changed the client needs to ask the user for login credentials in a corresponding dialog. The dialog shows "user" and "password" fields.
The dialog opens, but no input fields are available. Instead, a narrow blue line shows at the top, see attached screenshot.
(The "blue" might be due to our facilities customized theme of the nextcloud login screen, which is moistly light blue)
Client version:
Operating system: macOS
OS language: English
Installation path of client: /Applications/nextcloud.app/Contents/MacOS/

Hi,
It's same for me.
Version 2.6.4stable
MacOS 10.15.3
See you soon !
Same for me as well.

MacOS 10.15.3
Same for me. Installing on a new MacPro (Catalina), the latest version did not allow me to login, had to reinstall using 3.6.1.
Once the login is saved, I was able to upgrade to 2.6.4 and everything keeps working

That's indeed true – guess this indicates that some change to the login dialog seems to be the issue.
So apart from not showing the dialog when logging out, it also doesn't show the dialog after first installation or whenever opening the client without being logged in? So it is basically preventing the user to login?

correct
Are there any updates on this? Currently stuck with version 2.3.3.
This (my) report seems to be a duplicate of #1793 (which is only for 2.6.3., but seems to report the same issue).
@jokuha thanks for pointing that out! I will mark this as a duplicate then. Could you move relevant information from this issue like the screenshot to #1793? Afterwards this can be closed.
Duplicate of #1793
Moved most relevant info to #1793 and linked from there to here.
