I'm hosting Redis on railway (as my message broker for Celery), and very occasionally i'll get a random error:

Error while reading from roundhouse.proxy.rlwy.net:46385
ConnectionError
Error while reading from roundhouse.proxy.rlwy.net:46385 : (104, 'Connection reset by peer')

This doesn't appear correlated with our server load or anything else i can see (perhaps even inversely correlated with load?)
