Address Already in Use (Port Conflict)
Tags: ports, conflict, troubleshooting, server
Address already in use means another process is already bound to the server port. Stop the conflicting service or change ports.
Find the conflicting process
Windows: netstat -ano | findstr 26900
Linux: ss -lptun | rg 26900
Fix steps
- Stop any duplicate server instances.
- Change
ServerPort to a free port if needed.
- Update firewall and port forwarding rules after changing ports.
- Confirm telnet and web ports are unique too.
