SSL Connection not working

Question

When I connect to a server with an official SSL certificate, i get a

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

But when I run this app on an Android-phone, it works. Any solutions?

Best regards!

Answer 1

I found it out myself. Avast puts it own SSL certificate and Android does not trust this.
