Does the admin and nodes certs require same CA?

Using Elastic version 7.10.0
ODFE version: 1.12.0

I was trying to use a wildcard cert that we have obtained from godaddy for the node certs. I replaced all the required certs, params and dns settings for http and transport layer to get the wildcard cert working and was able to get rid of the cert warnings for port 9200 on my browser(or using -k in curl).

The problem is with the admin cert now: I tried using the old self signed admin certs to apply some new security settings and I was NOT able to get it applied. This makes me think is there a requirement that the CA for both nodes and admin cert should be same ?

Which root CA did you use with security admin user? GoDaddy or self-signed?
