Azure Redis connection failure when using SSL - azure

Question

I am using Spring Session with Redis using Azure Redis.
Things are working fine with the non-SSL port 6379. However with the SSL port 6380, I get this error:
ERROR (org.springframework.data.redis.listener.RedisMessageListenerContainer:651) || - Connection failure occurred. Restarting subscription task after 5000 ms
That’s it. No further information.
Here is my Redis configuration:
<bean id="redisPassword" class="org.springframework.data.redis.connection.RedisPassword">
<constructor-arg index="0" value="${spring.redis.password}"/>
</bean>
<bean id="redisStandaloneConfiguration"
class="org.springframework.data.redis.connection.RedisStandaloneConfiguration">
<property name="hostName" value="${spring.redis.host}"/>
<property name="port" value="${spring.redis.port}"/>
<property name="password" ref="redisPassword"/>
</bean>
<util:constant id="configureRedisAction"
static-field="org.springframework.session.data.redis.config.ConfigureRedisAction.NO_OP"/>
<bean id="lettuceClientConfiguration"
class="org.springframework.data.redis.connection.lettuce.DefaultLettuceClientConfiguration"
factory-method="defaultConfiguration">
</bean>
<context:annotation-config/>
<bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"
p:configureRedisAction-ref="configureRedisAction"/>
<bean class="org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory">
<constructor-arg index="0" ref="redisStandaloneConfiguration"/>
<constructor-arg index="1" ref="lettuceClientConfiguration"/>
</bean>
What is causing the connection failure?
