7. If you get an error that looks like: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure, add:

#PackagerProperty: IncludedModules = jdk.crypto.ec

may solve the problem.

Dear @Erel, I'm experiencing issues using my app with jOkHttpUtils2 outside B4J if I build the standalone package. I have already read other posts in this forum but I'm not sure how to proceed. I'm using the last version of B4J with openJDK 11 as written in the installation guide. I'm using...

i tryed with

#PackagerProperty: IncludedModules = jdk.charsets, javafx.web, jdk.crypto.ec

and with

SetSystemProperty("deployment.security.TLSv1.2", "true")
    SetSystemProperty("https.protocols", "TLSv1.2")

in AppStart, but it gives the same error

What happens when you run it from the IDE?

Might be a firewall issue.
