Возникла проблема при развертывании моего приложения Java Maven Spring-Boot в Google App Engine.

Мой pom.xml :

Мой appengine-web.xml : 

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <version>1</version>
  <threadsafe>true</threadsafe>
  <runtime>java8</runtime>
</appengine-web-app>

Я добавил ServletInitializer.java под моим основным приложением, что делает его отлично работающим в mvn appengine: run . Он также отлично работает в mvn spring-boot: run .

Мои application.properties : 

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=create
spring.jpa.hibernate.show-sql=true

spring.datasource.url=jdbc:postgresql://35.200.222.222:5432/test
spring.datasource.username=postgres
spring.datasource.password=Welcome1!

spring.datasource.initialization-mode=always
spring.datasource.initialize=true
spring.datasource.schema=classpath:/schema.sql
spring.datasource.continue-on-error=true

Ошибка : 

PSQLException: The connection attempt failed.
