Certificate signed by an untrusted issuer

Certificate is stating this error:

This certificate was signed by an untrusted inssuer

The issuer was my subCA (we have an offline rootCA) as well.

I apologize, I don't know much about PKI Infrastructure and how to troubleshoot this but.... if someone could point me in the right direction, I'd greatly appreciate it.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Where did you get this? This is most likely caused by self-signed certificates, as you mentioned that is was your subCA. do the clients trust this as a root CA?
what happened here is your sub ca certificate or / and root ca certificate is not installed on clients trusted root certificate store and hece you are getting abovee rror

U need to install root ca cert and sub ca certificate public key on affected machine or on all machines by group policy
