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

回答1:

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
)
