WSO2 API Management – Docker Compose – Login error after installation using default parameters

  docker, wso2, wso2-am

I can’t login to WSO2 API Manager after installation.

I perform the installation as indicated in these steps:
API Manager for Docker Compose.

According to the instructions:

Running the product: Once WSO2 API Manager is successfully deployed,
access the following URLs on your favorite web browser using the
credentials username: admin and password: admin.

Try to login in https://localhost:9443/carbon/admin/login.jsp

I try, using user: admin password: admin, but I have this error message in the log:

api-manager_1 | [2021-02-20 03:19:36,643] ERROR – AuthenticationAdmin System error while Authenticating/Authorizing User : java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

What am I doing wrong? thanks in advance.
