Not sure if you micht run into this same problem, but I got everything working on my mobile (J5) using Firefox, but everything failed on Chrome.Now it works!!,
I followed this steps, exported the certificate as pfx and later used java keytool to import it as a JKS file with this command:
keytool -importkeystore -srckeystore C:\SSLCerts\mycert.pfx -srcstoretype pkcs12 -destkeystore C:\SSLCerts\mykeystore.jks -deststoretype JKS
i got a JKS file and use it in the code of the jRDC server:
srvr.SetSslConfiguration(xSr,17179)' a different port of the common 17178 jrdc uses?
In the web page with the url test connection now i see the connection successful, with the padlock icon

But, there is a problem, in the B4A App with the endpoint:
javax.net.ssl.SSLHandShakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found
What is that?
Cleaning the history (cache) did not make any difference. After re-installing Chrome on my mobile suddenly everything worked also from Chrome.
