How to fix password problem with CockroachDB and Spring-Boot - postgresql

username: myuser
password:
jpa:

I created two users. One with no password and one with a password in database "mydb" on cockroachDB. Both are not working. Append "?sslmode=disable" to the url in spring.datasource.url also not working.
Exception without password:
org.postgresql.util.PSQLException: The server requested password-based authentication, but no password was provided.
Exception with password:
Caused by: org.postgresql.util.PSQLException: FATAL: password authentication failed for user "myuser"
Thanks for any help

You have to use:// after postgressql in your datasource url.
Your datasource url should be
jdbc:postgresql://localhost:26257/mydb?sslmode=disable
