Hello everyone! First of all I am very new to all this, I was trying to find answer by myself byt I am failing in getting anywhere. I have simillar problem to Pete from this thread: http://community.jaspersoft.com/questions/817327/jasperserver-pro-aws-vpc-id-does-not-exist I have created the JRS instance and the RDS instance according to the recommendations / videos / tutorials. Reading answers that Pete got, I can confirm that both my EC2 and RDS instances are on the same VPC. They share the same security group too. My RDS database is MySQL The AWS Settings are 'Use EC2 Credentials' The database is listed in the AWS DataSource under Amazon RDS The database driver is 'org.mariadb.jdbc.Driver' As Pete I get this error while testing the connection.
