> ozone.om.https-port is set to 9875
> Blocked the port on one of the OM instance:
> {noformat}
> [root@ozn-kx4-3 ~]# sudo iptables -L
> 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
> [root@ozn-kx4-3 ~]# sudo iptables -A INPUT -p tcp --dport 9875 -j DROP
> [root@ozn-kx4-3 ~]# sudo iptables -L
> Chain INPUT (policy ACCEPT)
> target prot opt source destination
> DROP tcp -- anywhere anywhere tcp dpt:sapv1
> Chain FORWARD (policy ACCEPT)
> target prot opt source destination
> Chain OUTPUT (policy ACCEPT)
> target prot opt source destination{noformat}
> The affected node UI is getting 500, which is correct, but along with that
> other two OM UI Instances are also throwing the same even when the port is
> not blocked there.
