I am getting the above error on using the certificate with IP address. Is there something else I am supposed to do for creating a certificate with Ip address? What are the reasons for the Hostname not verified: exception

Could you provide more details about the certificate. Notably an IP address in subjectAltNames should be of type IP and not DNS. — Steffen Ullrich, Apr 22 '19 at 18:43
@SteffenUllrich yeah, its of type DNS. I have added more details. How could I change it to type IP? — tarun14110, Apr 22 '19 at 19:03
You cannot change an existing certificate. You would need to create a new certificate where you specify the type of the subjectAltNames entry as IP and not DNS. — Steffen Ullrich, Apr 22 '19 at 19:36

I was able to get it to work as suggested by Steffen in the comments, I added the domain IP address to subjectAltName with type IP.

openssl x509 -req -in certificate_sign_req.csr -CA myCA.pem -CAkey myCA.key -CAcreateserial -out signed_certificate.crt -days 1825 -sha256 -extfile <(cat <<EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names
[alt_names]
IP.1 = ${domain}
EOF
)
