I'm trying to set up a development network and am unable to get Firefox to properly load the SSl certificate I have set up. The SSL cert works in Chrome and Edge but not Firefox. In Firefox I get the following error: Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for localhost:5003. The certificate is only valid for the following names: 192.168.0.6, localhost, 127.0.0.1 Error code: SSL_ERROR_BAD_CERT_DOMAIN I don't understand why Firefox is treating the port number as part of the Domain name, ie why is the certificate good for localhost but not localhost:5003 ? Thanks in advance, Jordan
