Hello!

I am trying to deploy my python shiny app on an EC2 but am running into trouble actually launching my app from ShinyProxy. I have nginx set up as a reverse proxy and I am able to get to the shinyproxy landing page when I navigate to my domain but when I click my app I get the error :

```auto
Unable to connect
Firefox can’t establish a connection to the server at 127.0.0.1:3838.

```

I’m pretty new to this so if I am missing something obvious let me know. Thanks!

My application.yml:

```auto
proxy:
  title: Open Analytics Shiny Proxy
  logo-url: https://www.openanalytics.eu/shinyproxy/logo.png
  landing-page: /
  heartbeat-rate: 10000
  heartbeat-timeout: 60000
  port: 3838
  bind-address: 127.0.0.1 # Added the bind-address directive

      container-image: quipi
      port: 3838

Hi, just to be sure, are you still experiencing this problem? If I now go to [https://quipi.org](https://quipi.org) it does seem to work.

Hi,

Yes I managed to get it working! I reinstalled everything and it worked so not sure exactly what the issue was. Potentially some issues with permissions on the EC2.

Thanks!
