switch off the certificate verification because of SunCertPathBuilderException for private url with untrusted certificate

I have an own settings.xsd , but the certificate for the url is untrusted. I would like to switch off the certificate verification, because I get the following error.:

Error while downloading 'https://space.url.net/settings.xsd' to '/home/username/.lemminx/cache/https/space.url.net/settings.xsd' : '[sun.security.provider.certpath.SunCertPathBuilderException] unable to find valid certification path to requested target'.xml(DownloadProblem)

This is the xml file.

<?xml version="1.0" encoding="UTF-8" ?>
<settings
    xmlns="http://maven.apache.org/settings/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/settings/4.0.0 https://space.url.net/settings.xsd"

The issue provides an XML example whose schema download fails for https://space.url.net/settings.xsd with SunCertPathBuilderException. Start by locating the schema-download entry point and any existing certificate configuration; done should include a clearly documented, safely scoped way to handle this private URL and coverage for the reported failure.
