IPv6

[baileyscott]

Hello.
Thankyou for the code.
I managed to get this working reliably on an Ubuntu server. I have recently tried to set this up on Redhat and whilst I know there shouldn't be any differences I am a bit puzzled at the behaviour I have noticed.
When I issue the npm run start command everything spins up nicely but it only seems to be listening on the IPv6 any address rather than the 0.0.0.0 IPv4 address.
I've googled and tried various things but I just can't seem to find the right config to adjust?
Thanks,
Bailey
