I’ve created a simple Spring Boot application in IntelliJ and tested the connection with the AWS database, which gives me no error. After creating a MVN clean install, I test the jar in the command-prompt, which also gives me no error. Great, I can upload my JAR file to my AWS Environment. I go to Environment > Configuration > Edit Database, and select my database in the snapshot drop down. But my Environment wound connect to the database. I don’t get why it would work. I’ve been trying to run my app on AWS for days now and I feel I’m close, but don’t know how to solve this problem. Plz check out my log:
