WPDiscuz not working on custom page template

Hi,

I put in the following code to show comments on my landing page template (Astra theme) – which ought to work and does when WPDiscuz is deactivated:

// If comments are open or we have at least one comment, load up the comment template.
if ( comments_open() || get_comments_number() ) {
  comments_template();
}

I’ve checked that under Comments > Forms pages are selected for the forms.

On that page I listed (password to access is: clouded), the WPDiscuz form shows, but it doesn’t work and I can’t understand why.

Is there a reason you can think of?

Thanks
