Hi,  
we have some logs at elasticsearch which shows, some remote IP:port is connecting to our elasticsearch which is non-TLS.  
We are not able to find any services on those hosts.  
Is there any way I can block all non-TLS requests coming to our cluster on 3 nodes.  
We dont want to see those errors anymore, till we find and stop those services.

regards,  
Sunil.

Hi Sunil,

I can see that you have raised this with support too, so in the interest of not duplicating effort, let's handle this there. If you want, you can add a summary for your resolution afterwards for other folks that might have similar questions.
