Whisky firewall port

[Nemy1242]

Hi! I'm trying to install a program with Whisky on my Mac m1 and I get a firewall error saying that it can't open port 27027. Can someone help me fix this please? I've already tried disabling the Mac firewall and I don't think it's the router because I tried it on a Windows computer that's connected to the same network and it had no problems. Thank you very much.
