Without looking carefully at your code/logs, I'd suspect that an OS or
network firewall is getting in the way.  Would this apply in your case?

I'm not an expert in firewalls but this might tell you what any Linux
level firewall is doing:

  $ sudo iptables -L

Here is what that command reports on a "wide open" Debian system of
mine:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
