What are your network interfaces? Since Lwan couldn't find the configuration file, it'll try to bind to localhost:8080, and you might not have an entry for localhost in your /etc/hosts file (which is odd but possible). Try copying the lwan.conf file to the directory it is running on, and changing the listener line to read listener *:8080 { so that it tries binding to all interfaces, or listener 127.0.0.1:8080 { if you'd like it to listen only on that particular interface. Please ensure that this interface is up and running (check with either ifconfig or ip).

I'm not sure also if Lwan works under ARM correctly even if it manages to bind to a network interface. Some of the used tricks might only work on x86.
