I've followed the instructions in this post to configure this but redis status is always showing not connected. I tried to turn on diagnostics on redis cache instance but it doesn't even seem like any requests are getting to the service itself. Any ideas?
After some more investigation it looks like there is a thread that covers the majority of the scenarios on the plug in discussions page... I would read through this and ensure you have things in the properly place as well...
