The error io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information means nothing answered at the address and port Minecraft tried. Check these first:
- Sign in to the control panel at panel.chicagoservers.co and open your Minecraft server.
- Is the server running? If it's stopped, click Start. A big modpack can take a few minutes to start: wait until the Console tab shows a line starting with
Done, then join. - Is the address right, with the port? Click the address at the top of the server's page to copy it, and paste it into Minecraft with the port, for example
203.0.113.25:25566. See How to connect to your Minecraft server - Did the server crash? Open the Troubleshoot tab: it checks the server and its ports and reads the console for the reason. See My server won't start or keeps crashing: using the Troubleshoot tab
If the server is running and other players can join but you can't, a firewall on your computer may be blocking Minecraft. On Windows:
- In the search bar of the Start menu, search for firewall and open Windows Defender Firewall.
- In the left-hand pane, select Allow an app or feature through Windows Defender Firewall.
- At the top, click Change settings.
- Find every entry named Java(TM) Platform SE binary or OpenJDK Platform binary (there may be several) and tick Private and Public for each, along with the left-most checkbox.
- Click OK at the bottom of the window.
- Restart Minecraft and try to connect again.
Still refused? Try another network, such as a phone hotspot: some school, work and public networks block game ports.
