Android Question Certification Path not Found [Solved]

[khwarizmi]

Hi all

Refer to this tutorial, ImageDownloader - The simple way to download images, I got this error:

ResponseError. Reason: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found., Response:
Error downloading image: https://khw-solutions.top/images/OnlineInstitute/1.jpg
javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

I had doubts about the SSL certificate for my site,It does not appear in the title. so I tested it on the site:

SSL Checker

Use our fast SSL Checker will help you troubleshoot common SSL Certificate installation problems on your server including verifying that the correct certificate is installed, valid, and properly trusted.

The result was:
The certificate should be trusted by all major web browsers (all the correct intermediate certificates are installed).
And on the site:

The result was:
This site works only in browsers with SNI support.

Yes (certificate)

Can you try downloading image(s) from other sites to check if it is/isn't your site set-up?
For example: https://www.lego.com/cdn/cs/set/assets/blte8083bf1a8f1132d/60303_alt1.jpg

If it works elsewhere, your site set-up may be at fault, if it doesn't work you need to post a code snippet or better a sample project.

The code works fine on any other site, it seems to be the site settings.

1. Do I apply the steps mentioned on the ImageDownloader.bas or on Starter.bas?
2. what's workstation in my website?

Neither. Read it carefully, it has nothing to do with the code.
