Certificate "CN=" not found in certificate store of store type 'Directory' - by: CFrayneIonic

Hello,
I'm having an issue with certificates where none of my generated certificates are being recognized? Below is the exceptions I get when I attempt to Write, Read and Subscribe.

What's confusing me is that I have multiple certificates of "CN= " in that directory. Image below.

I've put multiple of these in the Trusted Root Certification Authorities store and it still throws the same exception so I don't believe it's an issue of trust. I've looked on the server host side and the server doesn't even seem to receive the certs as I can't find them in the rejected nor trusted folder on the server. My only guess here is this CrytographicException in the details of the certs but I'm not sure how to fix that. Image below.

Here are the specs of my project.
