I have the exact same problem...

Hey,I have been Noticing something weird.When I click on the "Multiplayer" Button,It shows the server,But It says "Can't resolve Hostname" And when I click the server and click play,It says "Failed to connect to server Unknown host 'http' And If I remove that and try again, It says "Failed to connect to server Unknown host 'businessmodpack.com' ". Anyone help please?I wanna play multiplayer on this modpack.
