I'm still having trouble connecting to my obfsproxy bridge; Any pointers would be appreciated. External scanning indicates that the correct ports are open except for port 443 but it's definitely open on the firewall.

All of the ports respond on the external IP except for 443 but I can connect via SSL on 9001. I don't understand how ORListenAddress is supposed to work: my bridge times out on 443 but when I comment out the ORListenAddress line it doesn't connect via obfsproxy at all.
Please advise.

Yes, I've opened the ports in the Google Compute Engine (see below). I'll follow up on their forum to make sure I've altered the firewall properly.
