Apparently Jacoco expects to find a server running on your local machine at port 6300. But it doesn't find one, hence those error messages.
So, do you have the server running on a different machine? Or do you have it running locally but on a different port? If that's the case then perhaps there are some ant parameters you need to provide, to tell Jacoco where the server is actually running. I would expect the documentation to describe those, if they exist.
Or maybe you didn't run the server at all? If that's the case then you should review the Jacoco documentation to find out how to do that.

My server is running locally on a different port.
I changed the port number and now it can connect.
