What's the output of
bin/elasticsearch-keystore list
?
You would need to
- 
set the
bootstrap.passwordto something withbin/elasticsearch-keystore -f add bootstrap.password - 
Restart the node, as the keystore is read on startup and changes to its values are not refreshed on runtime.
 - 
Run
bin/elasticsearch-setup-passwords interactive - 
You don't need the
bootstrap.passwordanymore so you can remove it withbin/elasticsearch-keystore remove bootstrap.password
