I’m running 3.1.0-beta6 and getting the following error:

```plaintext
Started GET "/" for 92.62.56.207 at 2023-07-20 13:15:36 +0000

```

Any ideas what I’m missing or is this a bug?

It’s this a [standard install](https://meta.discourse.org/t/142537?silent=true)? Do all requests do this? Any plugins?

Nope, this is a development install, running locally. All GET requests do this, POST requests go through fine. No plugins whatsoever, the error comes from within the middleware.

I analyzed the [standard install](https://meta.discourse.org/t/142537?silent=true) in much more detail and found that the docker image launcher uses `bundle exec config/unicorn_launcher -E production -c config/unicorn.conf.rb` to launch unicorn. I used `RAILS_ENV=production bin/unicorn` instead. I guess I missed the run configuration. Problem solved.
