I adjusted my password via hash.sh, but I am not able to updat the backend…it keeps giving me an error related to SSL, even when I am using plain http. Please advise.

```auto
./securityadmin.sh -icl-nhnv -cacert /etc/opensearch/root-ca.pem -cert /etc/opensearch/kirk.pem -key /etc/opensearch/kirk-key.pem -h 10.123.80.97 Security Admin v7
Will connect to 10.123.80.97:9200 ... done
