MDC not listening on ipv4 9980/9981but on ipv6

[maniel 0]

I just installed MDC on linux ova, cannot connect to it via https, here's netstat:

tcp        0      0 127.0.0.1:9977          0.0.0.0:*               LISTEN      1386/ERAMDMCore
tcp        0      0 127.0.0.1:9978          0.0.0.0:*               LISTEN      1386/ERAMDMCore
tcp6       0      0 :::9980                 :::*                    LISTEN      1386/ERAMDMCore
tcp6       0      0 :::9981                 :::*                    LISTEN      1386/ERAMDMCore

it seems it listens on needed ports but on ipv6 instead of ipv4, why? nothing else is listening on ipv4 ports 9980 and 9981, ipv6 is disabled on this system

found a solution: the service listening on ipv6 was not the problem, the firewall was, i just had to unlock 9980 and 9981 ports with `ip6tables` command instead of standard `iptables`:

ip6tables -A INPUT -p tcp --dport 9980 -j ACCEPT
ip6tables -A INPUT -p tcp --dport 9981 -j ACCEPT
