Hello everyone,
I have trouble to run a shiny app with rstudio server on a centOS server, i have this error message "Connection refused" on the shiny browser opened.

I have install shiny server (and httpd)for deploy my shiny app and rstudio-server for dev new shiny app on the same server centos : here are the different versions of this service.
shiny-server : v1.5.18.987 (Node.js v16.14.0)
R : 4.1.3 (2022-03-10)
CentOS Stream release 8
RStudio Server - 2021.09.1 Build 372- 2009-2021 RStudio, PBC "Ghost Orchid" Release (8b9ced18, 2021-11-08) for CentOS 8
My shiny app in /srv/shiny-server/ works fine, but when i connect to rstudioserver by browser (and ip:8787) and i run my app, i see a new windows with "Connetion refused" and they are no message in the terminal.
The button that indicates that the application is running is even activated in rstudioserver interface and i just see that on the terminal.
> runApp('test')
Listening on http://127.0.0.1:7880
My "test" application is a copy/paste of this Shiny - Hello Shiny! and the shiny directory is in my home directory.
I may have forgotten some information, if so, please do not hesitate, thank you for your help.
Best regard,
Quentin B.
