I believe your using self-signed certificates, Correct?
If so, when you generate them, you need to adjust you file like this.

keyUsage = keyEncipherment, dataEncipherment
keyUsage = nonRepudiation, digitalSignature, keyEncipherment in the section v3_req in file req.conf


distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no
# C = US
# ST = California
# L = Los Angeles
# O = Internet Corporation for Assigned Names and Numbers
# OU = IT Operations
CN =
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
DNS.1 =
IP.1 =

Hope that helps


it is working fine now

Glad you fixed your issue. What did you do to resolve this?


I did what you suggested and replaced the keyusage as mentioned in the request file to gererate the certificate.
Thanks again
