That error message usually points out that your application starting a webserver and handling requests correctly [1]. There is an example on how to deploy a Springboot application for Google App Engine Java 11 runtime here [2] (the repository is here [3]). I'd strongly advise you to check [2] and [3] and most importantly make sure that your application is running locally without any issues [4] prior to deploying to App Engine.
