Cloned Elastic Beanstalk environment failing with status Severe

Question

Hi, I have successfully created a multi-AZ ElasticBeanstalk environment with a Load Balancer, EC2, and RDS. This is a Java application using Spring Boot, with a MySQL database. Everything is working fine with this environment. I cloned this environment and the new environment is failing.
The status is Severe. The Health shows: "100.0 % of the requests are failing with HTTP 5xx." 
In the web.stdout.log, I see this error: "com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure"
When I try running the application, I get error: "502 Bad Gateway"
I restarted the app server, but didn't help. The original environment is still working fine.
Can anyone please help?
Thanks

I was able to answer my own question. The original EB environment had a custom property that referenced my RDS endpoint. In the cloned environment, I had to change that property to reference the new RDS in the cloned environment.
