I pass the ‘$Build.LinkUrl$’ variable to a powershell script (through a ‘Execute Program’ action) which then publishes the information to ‘slack’.
Unfortunately the variable expands to a URL starting with ‘[http://localhost/](http://localhost/)’ which is obviously no good for external clients.
Is there a configuration for this or is this a bug?

Yes, under admin, Continua Server, Properties, set the Server.HostUrl to [http://yourhostname](http://yourhostname) - this property is used when creating the linkurl
