ShinyProxy not serving on 8080 port.

I am trying to install ShinyProxy in a local server The application.yaml config I use

proxy:
  title: Open Analytics Shiny Proxy
  logo-url: http://www.openanalytics.eu/sites/www.openanalytics.eu/themes/oa/logo.png

  # Docker configuration

ShinyProxy is running as a service on port 8080.

● shinyproxy.service - ShinyProxy
   Loaded: loaded (/etc/systemd/system/shinyproxy.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2020-08-27 08:43:30 IST; 5 days ago
 Main PID: 31430 (java)

   CGroup: /system.slice/shinyproxy.service
           └─31430 /usr/bin/java -jar /opt/shinyproxy/shinyproxy.jar

However, if I curl the URL, it says

$ curl localhost:8080
curl: (7) Failed connect to localhost:8080; Connection refused

My docker is up and running on 2375 and I can spin up a test container and access it over browser. So that doesn’t seem to be the problem here. Could anyone help me out?

I figured out what the issue was. Looks like the port 8080 was not open to remote access. I use a CentOS server so I fixed this with

firewall-cmd --zone=public --add-port=8080/tcp

Tested if my app was accessible. Yes it was.

firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --reload

Saved the firewall settings. This, if added in FAQ would be really helpful. Closing this thread now.

Hi, @sarthi2395. I think you need to change authentication to “simple”.
