Thanks, that was it @John_B - I am coming across the same issue as this thread now though: Redis connection getting fall
Working in development, setting my REDIS_URL to the Render external redis URL, the app works perfect.
Deploying to render, my REDIS_URL set to either the external URL, or the internal Render URL, I get the following error:
Jul 19 02:25:18 PM Unhandled Rejection at: Promise {
Jul 19 02:25:18 PM <rejected> Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379

Code is the exact same as development. Any ideas?
