Haven't been able to figure out how to resolve this issue. I created the consul.yml config file, but haven't adjusted any of the default settings in that config file. I also setup a files.domain.com in domains.yml. I also went into the DB and deleted some feature flags that I changed since the problem started. Nothing seems to have resolved the issue.

Any help or insight would be greatly appreciated!

flushing the redis cash seemed to resolve the problem. Still not sure what actually caused the error to begin with.

How to do u flush redis cache?

[Graham Ballantyne]

You can issue a FLUSHALL command from redis-cli, or just restart your redis instance if you're not persisting it to disk.
