bitcoin core – How do I fix port accessibility issues to allow inbound connections on MacOS?

Tor doesn’t use the usual ipv4 or ipv6 connection ports, it uses ports 9050, 9051, and 9150. This may be why Tor is running. Perhaps the port is blocked by your ISP or your network’s firewall? You can solve this problem by using a VPN or proxy.

If you want to check the port, you will need to do this from an external location. There are online tools such as Nmap Online, Port Scanner Tool, and HackerTarget.com.
