This seems to me like you have a firewall blocking the connection somewhere. Have you opened the ports on the firewall of the machine running the relay? And if you run this at home, have you forwarded the ports on your router?
Btw, you should configure the torproject repository to get a newer version of tor.
Have you tried restarting it? You dont have an address in your torrc and in your log i dont see the message indicating the automated address detection. Try restarting it a couple of times and look for External address seen and suggested by a directory authority: <your address>.
I don’t know why, but this address detection just fails sometimes.
