If I put in the browser address bar: http://194.x.x.x/ -> I correctly get:

Apache2 Default Page 

If If put: http://194.x.x.x:8080/ -> I get :

This site can’t be reached194.x.x.x refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall

And:

root@vmi1046457:~# curl 194.x.x.x
curl: (7) Failed to connect to 194.x.x.x port 8080 after 22 ms: Connection refused

What should I do in order to be able to connect to 194.x.x.x:8080 ?

Answer 1

I changed from 8080:80 to 8080:8080 ( a brand new change in tileserver-gl settings)
