Kibana degraded, available on Kubernetes

Hey
I've had a problem with Kibana for a while now. I installed Elastic Stack on kubernetes using the operator. At first everything was fine, however, since some time in the kibana logs it started throwing such errors:

Unfortunately I can't trace the cause of these errors, has anyone perhaps had a similar problem?

Welcome to our community!

Is there more to the log before this? Is Elasticsearch responding?

Yes, Elasticsearch is responding. However, as you can see in the photo below, every now and then the connection to the elastic is broken.

Thanks, there's not a lot there that's helpful unfortunately.

Is there anything in the Elasticsearch logs at around this time?
