403 Forbidden on Form Submit

Hi,

I’m getting this weird error in console.

https://domain.tld/esignature/wp-json/contact-form-7/v1/contact-forms/4/feedback 403 (Forbidden)

This is my .htaccess;

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /esignature/
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_URI} !^/wp-json
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /esignature/index.php [L]
</IfModule>

# END WordPress

Any insights on this?
