hst.actionUrl virtual configuration Hippo CMS

Question

Following the instruction here, my website can display the contents fine. However, handling the form submission is current a problem.

I have virtual host set up in my environment. Rendering of contents is fine but form submission ends up in a blank page.

My form is at http://mysite.local/contact

My virtual host is http://mysite.local matches to http://localhost:8080/site

My form follows the developer trail:

<@hst.actionURL var="actionUrl"/>
<form id="" class="form" action="${actionUrl}" method="post">

When I click submit, I was redirected to a blank page: http://localhost:8080/contact?r14_r1_r1:u_u_i_d=5641b2fe-10ad-41b2-8f30-06d8a59ff451

Using my custom component, I printed out the serverName and it's "localhost"!

How do I configure it's in the Console so that my server is "mysite.local" instead of "localhost"?

@Override
public void doBeforeRender(final HstRequest request,
final HstResponse response)
throws HstComponentException {
super.doBeforeRender(request, response);

l.info(request.getServerName());

}

Updates: I've added the node as per Joeren's suggestion.

However it's still not working. I event removed the "localhost" node that was orginally under hst:hosts >> dev-localhost but it broke the Site site.

I've noticed that "hst:hosts" have hst:defaulthostname set to "localhost". I haven't dared to make the change because it would be irreversible I thought.

Updates:

My virtual host configuration (nginx) is as follows:

server {
      # listen 80;
      server_name mysite.local;

      location /site/ {
        proxy_pass   http://localhost:8080/site/;
        # include /etc/nginx/proxy_params;
      }

      location /cms/ {
        proxy_pass   http://localhost:8080/cms/;
        # include /etc/nginx/proxy_params;
      }

      location / {
        proxy_pass   http://localhost:8080/site/;
        # include /etc/nginx/proxy_params;
      }
    }

Passing the host name solve the problem! Thanks to Jeroen's comment.
There is no need to update the hst:hosts configurations in the console though.

I've updated my nginx config to as follows:

server {
      # listen 80;
      server_name mysite.local;

      location /site/ {
        proxy_pass   http://localhost:8080/site/;
        proxy_set_header Host            $host;
        proxy_set_header X-Forwarded-For $remote_addr;
      }

      location /cms/ {
        proxy_pass   http://localhost:8080/cms/;
        proxy_set_header Host            $host;
        proxy_set_header X-Forwarded-For $remote_addr;
      }

      location / {
        proxy_pass   http://localhost:8080/site/;
        proxy_set_header Host            $host;
        proxy_set_header X-Forwarded-For $remote_addr;
      }
    }
