Hosting a ShinyProxy R Shiny App

[PotcharaS]

Hello,

I am having a trouble reaching my landing page following this example:

https://www.r-bloggers.com/2021/07/how-to-set-up-shinyproxy-to-host-shiny-apps/

Basically, I can check that my Docker is running, ShinyProxy is running and I have set the firewall rule to allow connection from TCP:8080

Set Up of VM is uBuntu 20.0 LTS, with the most basic core and 10 GB disk space,

1) When connecting to https://xxx.xxx.xxx.xxx:8080  server took too long to response,
