Opensearch is showing the cluster health in Red Zone and is not responding from the endpoint url and giving the 502 bad gateway.
I tried to upgrade the cluster configuration, still it is showing in progress since last day. It is stuck at 14%. Not sure what is the issue because upgradation is also not happening.
There were 2 nodes in this cluster, but now I am not able to see a single one in the instance health. It was showing free disk space upto 74 GB. And it has very less data.
Near about 1 million only.
This is the managed service.
Version - OpenSearch 1.2
Opensearch is not working since 2 days, so kindly please help me to make it run again. Because I can not afford to delete this cluster and create new one.
