locally. ---

It seams that 8080 was bound to something even thou i cannot find to what. It works when doing it: kc.bat start-dev --http-port=9090 --verbose ---

If you want to find out what uses 8080 port you can listen ports using a tool like netstat or lsof MacOS or Linux: ```auto sudo lsof -i -P -n | grep LISTEN ``` or ```auto netstat -an | grep LISTEN ``` Windows Powershell: ```auto Get-NetTCPConnection -State Listen ```
