A.Dev :
I deployed a Spring Boot app on AWS Elastic Beanstalk. I am facing a 502 Bad Gateway error. I cannot find anything useful from the logs
/var/log/nginx/error.log
2019/02/10 02:12:54 [error] 3257#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: ...., server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:5000/", host: "...."
I do not have any html files for front-end. I just want to upload deploy the api to share the documentation from swagger ui.
A.Dev :
It's because server is listening to 5000, Adding "server.port=5000" to application.properties fixed the issue.
