Recently we upgraded one of our lower environment from 8.1.4 to 8.7.1. When tried to build the mobile app from the Channels and Interfaces section, it keeps failing to build. On the UI it says "Build failed. SSL problem." and we are getting the  "Can't connect to build server because of SSL error" exception in logs (attached the complete logs for reference). We have already tried the below steps to resolve the issue, but doesn't work --

1. Added the Java default trust store location to the Tomcat start up Java options - -Djavax.net.ssl.trustStore=C:\Program Files\Java\jre1.8.0_281\lib\security\cacerts and the -Djavax.net.ssl.trustStorePassword

2. Enabled SSL on the server setting and we are trying from the HTTPS url only.

3. Verified the cacerts trust store certificates and was able to locate the "Go Daddy Root Certificate Authority - G2" certificate, which should be there for connecting to the Pega Mobile Build Server.

Are we missing anything else to make sure the app build is successful? We didn't have this issue in 8.1.4 version.
