/user/login 403 You are not authorized to access this page

I'm using Drupal 10 with Nginx and Basic Auth.

On the user/login page, I get a "You are not authorized to access this page. 403" error.

I can see the menu, but I do not see the login form.

When I remove Basic Auth, everything works, but with Basic Auth, it does not work.

I have this in my config:

location / {    auth_basic "Restricted Area!";    auth_basic_user_file /example/example/.htpasswd;    try_files $uri $uri/ /index.php?$query_string;}

Any idea what the problem is?
