Thank you for your reply. We tried restarting which did not help. Based on your suggestions here: [Accidentally deleted .security index for x-pack](https://discuss.elastic.co/t/accidentally-deleted-security-index-for-x-pack/69844/3)

We followed the below steps.  
We tried to reset the passwords for the built in users so that the `.security-7` index will be recreated so that the authentication issue can be fixed :

```auto
# docker exec -u elasticsearch -it elasticsearch bin/elasticsearch-setup-passwords interactive
Failed to authenticate user 'elastic' against https://10.10.206.110:9200/_security/_authenticate?pretty
Possible causes include:
 * The password for the 'elastic' user has already been changed on this cluster
 * Your elasticsearch node is running against a different keystore
   This tool used the keystore at /usr/share/elasticsearch/config/elasticsearch.keystore
ERROR: Failed to verify bootstrap password

```

Tried adding the bootstrap user on both nodes :

```auto
docker exec -u elasticsearch -it elasticsearch bin/elasticsearch-keystore add bootstrap.password

```

and restarted elastcisearch 7.8.0 on both the nodes in the cluster :

# docker restart elasticsearch

again getting the same error when resetting the built in user passwords

```auto
# docker exec -u elasticsearch -it elasticsearch bin/elasticsearch-setup-passwords interactive
Failed to authenticate user 'elastic' against https://10.180.206.110:9200/_security/_authenticate?pretty
Possible causes include:
 * The password for the 'elastic' user has already been changed on this cluster
 * Your elasticsearch node is running against a different keystore
   This tool used the keystore at /usr/share/elasticsearch/config/elasticsearch.keystore
ERROR: Failed to verify bootstrap password

```

Could you please let us know for a possible solution ?
