I have a similar problem even when I set the firewall to allow all traffic. The same happens with VNC connections and print services. The only thing I’ve found that helps this is to disable the firewall. I have reinstalled multiple times and the firewall always causes problems. Do away with it and setup a standalone firewall (or linux (or none like me 😀 )).
Sorry if there is a way around this and I am ignorant.
Good Luck,
Robert
