Re: Unknown connection detected & Failed to process selector key
Hello Siva
If running in a shared cloud environment, you should put best security
practices in place to secure all of your servers from connections from
unknown hosts (iptables rules) especially on sensitive ports as databases
or Apache Ignite.
It does seem that this address in the range 10.0.0.0/8 is somehow belonging
to your organization.
It's very unlikely any cloud provider would share 10.0.0.0/8 among
different tenants.

Hi,
I am seeing below exception in our ignite thick client logs. I am seeing remote address 10.136.96.174 which is not in our ignite cluster list and what I infer from the below logs is that someone is trying to connect to out ignite instances. Please let me know if my assumption is wrong. Also is there a better way to handle these scenarios ? Appreciate any help/pointers on this.
