subdomain SSL trying to borrow cert from sister domain

    Hello there!
    I've followed the instructions for setting up SSL for the administration panel, munin and monit and everything for that works as expected. The issue I have is when I just try to visit that website without the special port or subdirectory, the connection fails.
    To clarify:
    https://sub.domain.com:8080/ - good cert
    https://sub.domain.com:8082/ - good cert
    https://sub.domain.com/ - bad cert, thinks its for domain2.com
    I've disabled the SSL and LE SSL options in the panel for that subdomain website and reenabled them to try to force a rebuild but when I visit the site, the resulting refusal error tells me that the certificate on sub.domain.com is for domain2.com; another site on the same server.

    This is the error I get when visiting the subdomain:
    Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for sub.domain.com. The certificate is only valid for the following names: discord.domain2.com, domain2.com
    Error code: SSL_ERROR_BAD_CERT_DOMAIN

    What's going on? What do I need to do to ensure that sub.domain.com has it's own certificate without breaking the other URL's using the certificate correctly?

    Thanks for your time!
