Password protected WP page - Struggle with cache issue

[rolandsdotter]

While using the nginx helper combined with redis we get a wierd issue with WP's default password protection for Wordpress pages. Any one that knows how i might solve it?

The problem is that the password protection doesn't a appear or that the password protected appears but you are not able to enter the page at all. The host is Loopia, boost php 7.4.
