Help needed to install rapido


I want to install rapido.plone into Plone 5.0.2 instance. Getting the following error in starting plone in fg mode. Please help.

ssp@mail:/opt/plone/zinstance$ sudo bin/plonectl fg

ZConfig.ConfigurationError: There was a problem starting a server of type "HTTPS erver". This may mean that your user does not have permission to bind to the por t which the server is trying to use or the port may already be in use by another application. (Address already in use)

This error message is obvious when you want to read it.

The configured http-address inside your buildout configuration is already taken.
Either your Plone is already running or another application is using the same port.

netstat -nap|grep LISTEN | grep -v LISTENING|grep

will tell more.

Either terminate the other process or assign a different http-address in your buildout configuration
and re-run the buildout process.
