Support & Bug Reports

I have solved this problem with this Commands (Fedora): sudo dnf install java-latest-openjdk sudo dnf install java-latest-openjdk-develsudo

Try other builds of it or report it to the creators  

My friends get this error: "Failed to connect to the server: finishConnect(..) failed: Connection refused". The server is modded, and runs on my system, i also turned off the firewall. My friends join the server through playit.gg.
