I have created a new project with Spring Initializr:

  • Project: Gradle Project
  • Language: Java
  • Spring Boot: 2.7.4
  • Packaging: JAR
  • Java: 8
  • Dependencies: Spring Boot Actuator, Spring Data JPA, Spring Web, H2 Database, PostgresSQL Driver, Spring Configuration Processor

When I run the application I see the following:

  • Output from IntelliJ IDE indicates to go to http://127.0.0.1:64694/VAADIN/ enter image description here
  • Next, open Chrome Browser and navigate to the URL: Web page 1 of 2
  • Wait a second or two and the web page displays and just sits there: Web page 1 of 3
  • After waiting for a while, look back at the output from the IDE: enter image description here

Getting the error:

How could I get around this error?

The correct URL is http://localhost:8080

The other is an internal debug url
