Getting SSL error while opening untrusted SSL link in XWalkView (CrossWalk)

Question

I'm using crosswalk as an alternative to webview in android for an application that has builtin mini browser and require lots of web navigation.

Problem:

Now whenever I try to navigate to a SSL based a dialog pops up saying SSL Certificate Error Alert and then stuck after that.

My Gradle

dependencies {
 implementation fileTree(dir: 'libs', include: ['*.jar'])

 //noinspection GradleCompatible
 implementation 'com.android.support:appcompat-v7:27.1.1'
 implementation 'com.android.support.constraint:constraint-layout:1.1.2'
 implementation 'org.xwalk:xwalk_core_library_beta:18.48.477.13'

 testImplementation 'junit:junit:4.12'
 androidTestImplementation 'com.android.support.test:runner:1.0.2'
 androidTestImplementation 'com.android.support.test.espresso:espresso- 
 core:3.0.2' 
}

My Code:

XWalkView xWalkView = findViewById(R.id.xwv_browser);
    xWalkView.setUserAgentString("Browser/1.0 Android");
    xWalkView.load(WEB_URL, null);

Any help, code, concept would be appreciated. Thanks in advance
