Try to delete DB files (test.mv.db and test.trace.db). Maybe you have created it before and used for it different credentials.

The following worked for me:

H2 console screenshot

  1. Remove and re-add Saved Setting and Setting Name [Generic H2(Embedded)] (see screenshot above)
  2. Make sure the JDBC URL, Username, Password match your application properties.
  3. Update, build and restart Spring Boot Application.

Also, delete browser history, cache, etc.,

Sample Application. Properties

spring.h2.console.enabled=true
spring.datasource.url=jdbc:h2:mem:dcbapp
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
