Liveness probe failed when using lettuce instead of jedis in spring-starter-data-redis - spring

Question

I have a spring boot application using spring cloud bom : Hoxton.SR1
The app is deployed in a kubernetes cluster.
To connect the app to the redis database I tested 2 different configuration :
Jedis connection pool configuration :
pom.xml :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
<exclusions>
<exclusion>
<groupId>io.lettuce</groupId>
<artifactId>lettuce-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- jedis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
application.yml :
spring:
redis:
host: localhost
port: 6379
password: password
database: 0
jedis:
pool:
min-idle: 0
max-idle: 12
max-active: 12
max-wait: 500ms
Deployment in the K8S cluster works well.
Lettuce connection pool configuration :
pom.xml :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<!--lettuce connection pool-->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>
application.yml :
spring:
redis:
host: localhost
port: 6379
password: password
database: 0
lettuce:
pool:
min-idle: 0
max-idle: 12
max-active: 12
max-wait: 500ms
Deployment in the K8S cluster DOES NOT WORK, error is : Liveness probe failed: Get http://10.68.13.246:8080/actuator/health: net/http: request canceled (Client.Timeout exceeded while awaiting headers).
What am I missing ?
What could be the root cause of this ?
Is it related to spring actuator or lettuce connector ?
