REST params (formData) are not available when using HTTPS POST

[NadigNikhil]

We are runnig a Ubuntu 18.04 Server with nginx. I send the following ExtJS AJAX request to our application via HTTPS:

Ext.Ajax.request({
     url: 'https://localhostl/test/setTaskLock/15/true',
     method: 'POST',
     headers: {
        'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
     },
     params: {
         test123: 'answer123'
     },     
     success: function (response) {
         console.log("success");
     },
     failure: function (response) {
         console.log("failure");
     }
});

We have migrated from 2.3.7 to 2.4.0 and observe that the formbody is missing. While we use HTTP, we get the desired output and issue is there when we try to make the rest call using HTTPS.

Below is the maven dependencies:
<restlet.version>2.4.0</restlet.version>

org.restlet.jee org.restlet ${restlet.version} org.restlet.jee org.restlet.ext.crypto ${restlet.version} org.restlet.jee org.restlet.ext.fileupload ${restlet.version} org.restlet.jee org.restlet.ext.servlet ${restlet.version} org.restlet.jee org.restlet.ext.xml ${restlet.version} org.restlet.jee org.restlet.ext.wadl ${restlet.version} org.restlet.jee org.restlet.ext.jaxb ${restlet.version}

Same here. We reproduced this behaviour also with JQuery but also see it with a http proxy server. Any timeline to fix this (possible critical) bug? thanks a lot!
