3. The problem I’m having:

I have wild card certificates for domain *.edjx.com, so I should be able to access sub1.edjx.com and sub1.sub2.edjx.com also.

subjectAltName does not match sub1.sub2.edjx.com

• SSL: no alternative certificate subject name matches target host name sub1.sub2.edjx.com

5. What I already tried:

I have tried

                     
                        {
                            "match": {
                                "sni": [
                                    "*.edjx.com",
                                    "*.*.edjx.com"
                                ]
                            },

*.*.edjx.com isn’t a valid certificate. You can only have *.edjx.com or *.sub.edjx.com, *.sub2.edjx.com and so on. RFC 6125 specifies that the * must be in the left position and only one can exist per name.
