Bungeecord IpTable issue

Hi, so my bungeecord works fine, you can connect to it without issue, but it reads my other servers as offline and I am not sure why. They're all in the same machine and I made sure the ports they're running on are open, but nonetheless bungeecord still thinks the servers are offline despite the servers themselves showing that they're live (Yes, they have the right ip and port in bungeecord)

Is there something I'm possibly forgetting in iptables? Thanks.
