Need help installing SSL to Windows Exchange 2019 Server

Job ID: 31977675

Budget: $30 – $250 USD

I have a wildcard SSL certificate I am having trouble installing on two windows exchange 2019 servers.
I have the cert as string, suspect it's just encoded wrong since I am getting a base64 encoded error message.

I've installed the certificate on my DirectAdmin machine and it's working there. So would like some assistance in moving it to my exchange servers :)
