Our cluster fe2023 stopped working after an update, and creating a new index with a custom script.

One of the nodes is fully working, but it's bloated because of the high access is having. (Mem pressure \> 100%). We tried adding more Data centers. But no change at all.

We're not being able to access Kibana, or any other tool to know what's happening.

I think this is the error you should be looking into:

Is every node in your cluster of the same Elasticsearch version?
