following up on live_query and run blank screen in the UI problem I had from a week or 2 ago. turns out it's because our elasticache redis uses in-transit encryption. fleet ui thought all was good with redis because it was able to connect to the remote redis cluster. but turns out it was not able to talk to encrypted redis.
once I created a stunnel between fleet:6379 and elasticache:6379, then told fleet to use localhost:6379 for redis, live_queries work now. 🎉
