Tor is not using the usual ipv4 or ipv6 connexion ports, it use the 9050, 9051 and 9150 ports, it can be why tor is running, maybe the port is blocked by your ISP or a firewall in your network ? you can try using a VPN or a proxy to go arround this problem.
To check your port you gonna need to do this from an external location, here is some on line tool: Nmap Online, Port Scanner Tool, HackerTarget.com
