Once Server Finder is done, and you go back to the server list, you will notice that some of the servers it found will be broken. Wait until all servers are done loading, so that you can see which ones are working and which ones aren't.

Then click the “Clean Up” button and run a Clean Up with the default settings to get rid of the broken servers.
