how to start:

sudo start shiny-server

tail /var/log/shiny-server.log

[INFO] shiny-server – Starting listener on http://[::]:3838
[ERROR] shiny-server – HTTP server error (http://[::]:3838): listen EAFNOSUPPORT :::3838
[INFO] shiny-server – Shutting down worker processes

change the shiny-server config

/etc/shiny-server/shiny-server.conf

change:

server {
listen 3838;

…

to
