Glide - javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found

The issue is about certificate follow this link -https://stackoverflow.com/a/39032433/4741746

This will bypass certificate and allow you to enter in system

see this link also -https://futurestud.io/tutorials/glide-module-example-accepting-self-signed-https-certificates

Create your custom GlideModule Class,OkHttpUrlLoader class and attach to you Glide as mention in above link

You have to put

<meta-data
        android:name="io.futurestud.tutorials.glide.glidemodule.CustomImageSizeGlideModule"
        android:value="GlideModule" />

Inside application tag of your AndroidMainifiest file https://github.com/fs-opensource/android-tutorials-glide/blob/master/app/src/main/AndroidManifest.xml

Create class UnsafeOkHttpClient.java

public class UnsafeOkHttpClient {
public static OkHttpClient getUnsafeOkHttpClient() {

        // Install the all-trusting trust manager
        final SSLContext sslContext = SSLContext.getInstance("SSL");

        // Create an ssl socket factory with our all-trusting manager
        final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        OkHttpClient.Builder builder = new OkHttpClient.Builder();

Add app/build.gradle

implementation 'com.github.bumptech.glide:glide:4.10.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.10.0'
implementation("com.github.bumptech.glide:okhttp3-integration:4.2.0") {
    exclude group: 'glide-parent'
}

In AndroidManifest.xml

<application>
<meta-data
        android:name="Replace_your_package_name.UnsafeOkHttpClient"
        android:value="MyGlideModule" />
</application>

For Glide 4

@GlideModule
public class MyGlideModule extends AppGlideModule {

    @Override
    public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {

        //To Attach Self Signed Ssl Certificate
        /*OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .sslSocketFactory(sslSocketFactory, X509TrustManager)
                .build();*/

        //Unsafe Okhttp client
        OkHttpClient okHttpClient= UnsafeHttpsClient.getUnsafeOkHttpClient();

        registry.replace(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(okHttpClient));
    }
}
