Failed to validate connection Pooled connection wrapping physical connection (Connection has been closed.). Possibly consider using a shorter maxLifetime value.

Hi everybody, I am working on a Spring MVC project (Spring version 4.1.1) and I configured HikariCP as connection pool manager. When the application is not used for a while, it seems like Hikari starts loosing connections with DB, and when I try to connect to the web app, Tomcat shows this:

Here is my Hikari datasource configuration for Spring:

I already tried to use shorter maxLifetime values, as suggested by the stacktrace, but it did not make any difference.

Could anybody please help me resolving this issue? What am I doing wrong?

Other useful info:

• HikariCP version: 3.3.1
• Java version: 1.8
• Tomcat version: 8.5
• Spring MVC version: 4.1.1
• JDBC PostgreSQL driver version: 42.2.16
• DBMS version: PostgreSQL 13.0
