Can't add new users

Clicking on the create button to add a new user doesn’t seem to be doing anything. I’m able to add a new group but not a user.

I am also having the same issue. Can add new groups but not new users. I have been able to add users before until recently. Only thing I can think of is maybe an update happened in the background that might have caused it.

Running Nextcloud version 11
Happens on multiple browsers, multiple computers
Using the admin account which can do other adminy things.

Actually I was just able to add a user. I simply had to make the password more complex.

This can be a problem when you have not properly configured your nginx webserver:
