I have a ELK 8.4.3 Main Cluster  
I have ELK self-monitoring enabled on this cluster

another ELK 8.4.1 Remote Cluster, on a separate machine, which is not online all the time  
I only use this cluster to offload data from main cluster

* * *

## The problem only occurs when the remote cluster is offline.

When I try to access the monitoring dashboard on the Main Cluster, I got nothing and an error.  
The error logs are shown in the screenshot

I think remote cluster does not have anything to do with self-monitoring, but this is preventing me from using it

I feel that there is some issue with name resolving/connectivity/route tables.  
Because it is giving "No route to host".  
Try to check whether that IP(x.x.x.66) port 9300 is connecting.

Hi @edwardcccc ,

Is the Remote set with `skip_unavailable: true`?

If it is and you're still seeing failures you may want to set the tcp retries on the Main cluster OS as shown on [TCP retransmission timeout | Elasticsearch Guide [8.4] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/system-config-tcpretries.html)

As long as the Main cluster can respond to a query when the Remote cluster is down, the stack monitoring UI should load.

Alternatively if the `.monitoring-*` indices all stay on the Main cluster, you can set `monitoring.ui.ccs.enabled: false` ([reference](https://www.elastic.co/guide/en/kibana/current/monitoring-settings-kb.html)) which will make Stack Monitoring UI load using only indices from the Main cluster.
