Hi,

we’ve been trying to set up backup to S3 in the 1.4 stable version, hosted on [Communiteq](https://www.communiteq.com) (formerly DiscourseHosting). Our access keys are correct and we can upload through their CLI. However, Discourse throws the following errors (see dump below).

We found an issue that seems to be related:

[https://github.com/aws/aws-sdk-ruby/issues/923](https://github.com/aws/aws-sdk-ruby/issues/923)

Any ideas?

```

tests-passed and beta are not affected by this bug. Our hosted customers have this fix.

I am torn on updating this gem on stable, it feels like a bit of a risky move.

Sorry, I don’t entirely understand what you’re saying. It’s correct that this is currently broken in 1.4 stable?

Requires a gem update, is how I read it. Not our bug, technically, but requires recompiling against a newer gem version that handles this particular task.
