Couldnt resolve the gradle sync ERROR: Cause: unable to find valid certification path to requested target

I am getting a build error “ERROR: Cause: unable to find valid certification path to requested target”. I have deleted the expired certificates from the settings->certificate page. Also, I have updated the gradle build with maven { url “http://jcenter.bintray.com”}. I am still getting the build error. Please help in fixing the same. I followed the resolution provided in the Error:Cause: unable to find valid certification path to requested target , but no luck.

Gradle.build file :

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
        maven { url "http://jcenter.bintray.com"}
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        //jcenter()
        mavenCentral()
        jcenter{ url "http://jcenter.bintray.com/" }
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Hi @rbeatajane,

Your build needs to use HTTPS instead of HTTP in your repositories blocks.

JCenter dropped support for HTTP on January 13th, 2020.
