Hi all,

I have a tribe node setup across two clusters, on server0 ($IP0) and  
server1 ($IP1), using unicast discovery.  
server0 also runs the elasticsearch tribe node instance.

This setup works fine most of the time, and I can see logs from all  
clusters on tribe node Kibana.

The issue is that sometimes the elasticsearch instances go unresponsive.  
More specifically, it's the nodes API (including /\_cat/nodes) that do not  
respond, which results in Kibana throwing the following error message:

Could not reach http://.../\_nodes. If you are using a proxy, ensure it is

> configured correctly

At first, I thought it was just the tribe node that was doing this, but  
just today I noticed this on one of the clusters as well.  
Other URLs don't seem to be affected (e.g. /, /\_cluster/health, etc).

After some time, the nodes API comes back and produces the following  
output, and goes unresponsive again.  
I've also tried restarting the elasticsearch processes. While it fixes the  
unresponsiveness in the short term, it then goes back to the same cycle.

Any help would be greatly appreciated.
