java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. while loading image in Glide

Question

Image not loading with Glide, after migrated the server from HTTP to HTTPS. But the images are loaded in Browser correctly.

Dependency:

implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'

Simple image load:

Glide.with(Context).load(imageUrl).into(imgView);

How can I overcome this??

I came to glide after tried the Picasso. I need a solution for Glide itself — Gowri sankari, Feb 10 '20 at 10:33
Can you load the same HTTPS URL in a browser? I would anticipate you will have problems also. I guess your problem is not with Glide, or anything in the app, but with the cert that the server responds with. — kenny_k, Feb 10 '20 at 10:35

i think the server hosting the file (backend server) is not trusted by REST client (Retrofit). Short term solution to continue development is to trust all certificates but for Production environment you will have to trust exact certificate of your backend (hosting images), this is usually done by either bundling certifcate file or its fingerprint. Please refer here for sample implementations shared in other threads.

The issue is about certificate. You need to create your custom GlideModule Class,OkHttpUrlLoader class and attach to you Glide as mention in the link below

https://futurestud.io/tutorials/glide-module-example-accepting-self-signed-https-certificates

Then you have to put the following in your manifest file

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

Check the example https://github.com/futurestudio/android-tutorials-glide/blob/master/app/src/main/AndroidManifest.xml
