Ergo full node listens only tcp6 [solved]

Hi There!

just started to full node and tries to access
but I realized that node only listens on tcp6:

~/ergo$ netstat -ltna | grep 9053
tcp6       0      0 :::9053                 :::*                    LISTEN 

so how can I force the node to listen on tcp4 as well?

Thanks, Balazs

false alarm - it listens on everywhere just had a VPN on the client machine that is why I could not reach it.
Great work - thanks!
