Hi,
I’m using the official docker image for Keycloak and I have a problem.
I have received every time the same error:
Caused by: java.io.IOException: Connection reset by peer, Authentication lapse 0 ms.

Keystore is properly mounted, but when it was missed in a different java application it was visible in the logs. My JDBC URL template:
<connection-url>jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=${env.DB_PROTOCOL:tcp})(HOST=${env.DB_ADDR:oracle})(PORT=${env.DB_PORT:1521}))(CONNECT_DATA=(SERVICE_NAME=${env.DB_DATABASE:XE})))</connection-url>
Everything works properly with default(tcp).
