SSL Cert BAD_CERT_DOMAIN Prefix?, With SAN, Local CA, Local DNS Redirect

Time:09-10

I've got a couple of Services running internally with Certs issued by a Windows Server.
They all work with Chrome Edge, just not with Firefox.

as an example, there's a db on the network accessed by going to https://db
It's CommonName is {FQDN}
It's SANs are db, database, {IP}, {FQDN},

as I said, works fine with Chrome Edge, but when I use Firefox I get this error:

https://db/

Unable to communicate securely with peer: requested domain name does not match the server’s certificate.

I assume it's because of the https? ..I've seen issues fixing www with *db, but nothing about https ..or maybe this is completely the wrong route, not sure.. has anyone else come across this?

any direction or advice would be appreciated!

Note: I can provide how I generated the certs if it's a possible settings thing, I wrote a step-by-step guide :D

Firefox does not like IPs in AltSubjectNames. Removing them makes the setup work
