Deploying SpringBoot on AWS Beanstalk - app starts, connects to RDS-DB, but browser can't connect

votes

I'm learning AWS right now and therefore now deployed my spring boot app on AWS Elasctic Beanstalk and connected it to my mariaDB Database that I put on AWS RDS. That was successful! I can see the test entries in my database and also the Elastic Beanstalk log file shows me that the Spring app has started and the health check is OK.

But when I click on the link to the App studileih.eu-central-1.elasticbeanstalk.com, I get a 404. I also tried studileih.eu-central-1.elasticbeanstalk.com/5000, since my spring boot app is starting on port 5000 (I changed it from 8080 to 5000 because I think ElasticBeanstalk needs port 5000?) studileih.eu-central-1.elasticbeanstalk.com/allProducts and studileih.eu-central-1.elasticbeanstalk.com/5000/allProducts since /allProducts is the endpoint for my get request.

Elastic Beanstalk Health Check

I thought I had set the security group inbound rules to "Allow All Traffic from Everywhere" already, but that was wrong. After adding them it worked with http://studileih.eu-central-1.elasticbeanstalk.com/allProducts (port 5000 is not needed) It's weird that the HTTP rule wasn't enough tough...:

my security group inbound rules

That's the result directly in the browser:
