<p dir="auto">
I have a VPC that is setup on AWS with two EC2 machines running, Machine A and Machine B. RabbitMQ and a celery producer lives in Machine A and the celery workers are living in Machine B. The celery producer pushes in tasks into RabbitMQ via localhost on TCP port 5672. The workers are having trouble authenticating themselves with RabbitMQ on port 5671. I get a SSLv3 handshake error.

<h1 dir="auto">Expected Behavior</h1>

<p dir="auto">I read that the latest version of Erlang/RabbitMQ should not be accepting SSLv3 due to some vulnerabilities, so I am not sure why Celery is trying to authenticate with SSLv3. In the RabbitMQ configuration file, I specified to not use SSLv3 authentication and also reject connection if the client (in this case, celery) cannot produce a certificate.</p>
<h1 dir="auto">Actual Behavior</h1>

<p dir="auto">When I start up my celery worker, I would get this error message</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="consumer: Cannot connect to amqps://USER:**@rabbit-endpoint.com:5671//: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:847)."><pre class="notranslate"><code class="notranslate">consumer: Cannot connect to amqps://USER:**@rabbit-endpoint.com:5671//: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:847).
</code></pre></div>
<p dir="auto">I get this message when I set this RabbitMQ configuration:<br>
<code class="notranslate">{fail_if_no_peer_cert, true}</code></p>
<p dir="auto">However, the error goes away if I change the RabbitMQ config to:<br>
<code class="notranslate">{fail_if_no_peer_cert, false}</code><br>
But what is the point of using TLS if people can just connect to my RabbitMQ without providing their SSL certificates</p>

<h1 dir="auto">Brief Summary</h1>

<p dir="auto">I would like to be able to configure <code class="notranslate">health_check_interval</code> (i.e.: <a href="https://github.com/andymccurdy/redis-py/blob/1a41cfd95a53a95b078084d8627be6b6fba3bb71/redis/client.py#L737-L749">https://github.com/andymccurdy/redis-py/blob/1a41cfd95a53a95b078084d8627be6b6fba3bb71/redis/client.py#L737-L749</a>) for the Redis results backend</p>
<h1 dir="auto">Design</h1>
<h2 dir="auto">Architectural Considerations</h2>

<p dir="auto">None</p>
<h2 dir="auto">Proposed Behavior</h2>

<p dir="auto">This would be an opt-in configuration to Redis via Celery.  This lets us have more control over the Redis functionality and enables us to tune it to our desire.</p>
<h2 dir="auto">Proposed UI/UX</h2>

<p dir="auto">New environment variable that allows setting this value</p>
