MuseHub Is Having Trouble Connecting

Hi, I've downloaded and installed MuseHub onto my Windows 11 laptop and when I start it up I get the message "Something went wrong. MuseHub is having trouble connecting. Please check your internet connection and ensure any firewall you have is set correctly". I get the same message on a Windows 10 laptop so it's not device specific. Presumably this is a firewall setting. Can anyone provide me with the ports MuseHub needs to connect to? Many thanks
