Can not deploy Spring Boot with MySQL

So my application use mysql and i have the following error when i tried to deploy
org.postgresql.util.PSQLException: The connection attempt failed.


I’ve replied to the ticket you also opened, which has slightly different details.

You mention MySQL, but the message shared is from a Postgres util; they wouldn’t be compatible.

Let’s keep the conversation in one place (on the ticket). Then, you can update this post when we get to the solution.
