Hello fellow ShinyProxy users, I am fairly new to using ShinyProxy and after a few days’ tinkering I finally got the demo working on Ubuntu 20.04. However I came across an issue and hope someone know how to fix it. When I first tried to start ShinyProxy I got the “Port 8080 was already in use” error so I followed the FAQ and changed the port to be 9999. But then I got a “port 9090 was already in use” error. After some digging I found out port 9090 is being listened by Java. I managed to kill the process using this command
sudo kill -9 sudo lsof -t -i:9090
And then everything runs fine.
My question would be:
Why does this happen and how to avoid this extra step?
Here is more information about my system.
