Steps to Reproduce



Click 'BUILD' button on Mobile Apps screen.


Root Cause



The version of the JVM used to host PRPC lacked the Certificate Authority ("CA") Certificate in its truststore ("$JAVA_HOME\jre\lib\security\cacerts" file).

Resolution



Perform the following local-change:

Upgrade to a newer JVM which does include the required CA Certificate.

Since the Mobile Build Server uses an SSL Certificate signed by well-known ("Go Daddy"); this will be generally included with the platform [Java in this case] by default).

Check which CA Certs are used by the 'Mobile Build Server' using the following command:


openssl s_client -connect mobilebuildserver.pega.com:443 -showcerts

Then ensure that the 'cacerts' file for the had JVM included it.
Installing the latest (supported) JVM for the platform is the easiest thing to do (all things considered), but if this is not possible, then try importing the CA Certificate(s) into the 'cacerts' file instead.
