Images aren't caching correctly

[NotoriousGOR]

Hello,

I've forked this repository to create a MVP to demo how good this library is. I've never used Fly.io, nor Redis that much so I think I probably messed up the configuration somewhat. Serving locally on my machine works just fine, but when serving to Fly.io, the images aren't loading as you can see here:

Any idea what I may have done wrong? I created a persistent volume on my App which is tied to here:

[mounts] destination = "/app/.cache" source = "hive_volume"

And I also created a separate Redis app on the same team, but I am still having the same result. I'd really appreciate any help here.

Thank you @jacob-ebey !
