spring-boot actuator health-check mysql Java

I'm refactoring my project and I'm confused about After trying multiple solutions online, I still can't figure this out... This might be a silly question, but I'm experiencing issues with the Spring Boot Actuator health endpoint not returning the expected status in my production environment. The app is built using Spring Boot 2.5.4 and the health check is supposed to return 'UP' when all dependencies are healthy. However, it consistently returns 'DOWN' with the message `"want to connect to database"` even though the database connection is functioning correctly. I've verified that the datasource properties in `application-prod.yml` are correct: ```yaml spring: datasource: url: jdbc:mysql://localhost:3306/mydb username: myuser password: mypassword driver-class-name: com.mysql.cj.jdbc.Driver ``` I confirmed that the application can connect to the database by running a simple query in a REST controller, which works fine: ```java @GetMapping("/testDb") public ResponseEntity<String> testDb() { jdbcTemplate.queryForObject("SELECT COUNT(*) FROM my_table", Integer.class); return ResponseEntity.ok("Database is reachable"); } ``` Despite this, the health endpoint at `/actuator/health` continues to report the database as down. I've also checked that the `spring-boot-starter-actuator` dependency is included in my `pom.xml`: ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> ``` When running in a local environment, the health check works as expected. I've tried using `curl` to hit the endpoint and checked the logs, but there are no errors or warnings that provide insight into why the health status is incorrect. Is there a configuration or an environment-specific scenario that could result in this behavior? Any suggestions for troubleshooting this would be greatly appreciated. What am I doing wrong? This issue appeared after updating to Java stable. Any help would be greatly appreciated!
