Hi
You use a keystore in your configuration
and you get an error regarding the password of that keystore
So it probably means that your keystore is password protected ( you specified a password when creating this with elasticsearch-certutil ) and you need to specify this password in your configuration too, otherwise elasticsearch cannot read the keystore to get the keys and certificates from it. How to do this is already described in detail in our configuration, see the sections that start with
"If you secured the node’s certificate with a password..."
