title: Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer'
body: <p>I am able to connect to Azure Cache for Redis with the following Spring Session configuration:</p>
  
  <pre><code>&lt;bean id="redisPassword" class="org.springframework.data.redis.connection.RedisPassword"&gt;
      &lt;constructor-arg index="0" value="xxxxxxxxxxxxxxxx"/&gt;
  &lt;/bean&gt;
  
  &lt;bean id="redisStandaloneConfiguration" class="org.springframework.data.redis.connection.RedisStandaloneConfiguration"&gt;
      &lt;property name="hostName" value="acmedev.redis.cache.windows.net"/&gt;
      &lt;property name="port" value="6380"/&gt;
      &lt;property name="password" ref="redisPassword"/&gt;
  &lt;/bean&gt;
  
  &lt;context:annotation-config/&gt;
  &lt;bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"/&gt;
  
  &lt;bean class="org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory"&gt;
      &lt;constructor-arg index="0" ref="redisStandaloneConfiguration"/&gt;
  &lt;/bean&gt;
  </code></pre>
  
  <p>My app successfully connects:</p>
  
  <pre><code>[lettuce-nioEventLoop-4-1] DEBUG io.lettuce.core.RedisClient - Connecting to Redis at acmedev.redis.cache.windows.net:6380: Success
  </code></pre>
  
  <p>The app then hangs for a while and I eventually get this error</p>

  <p>These same beans work just fine when I use redis running on <code>localhost</code>.</p>
  
  <p>What am I doing wrong here?</p>
